Project Megafauna fossils from the Pliocene of Australia Australian Research Centre for Human Evolution This project will examine the unique 3.5 million year old megafauna fossils from Chinchilla Rifle Range, Queensland. The project will focus on the taphonomy of the site, and the sequence of fossils collected in systematically excavated sites. Several unusual fossils are awaiting description and taxonomic identification, and palaeoenvironmental proxies revealing ancient Australian habitats can be further interogated. Palaeontology EarthScience	Professor Julien Louys
Project Ancient DNA Australian Research Centre for Human Evolution This project aims to recover all the genetic information from four ancient humans. Two of these iconic specimens come from Australia and two from Malaysia. We will sequence the entire DNA (genomes) and proteins (proteome) of Mungo Man (Willandra), as well as the Yidinji King (Cairns), the Deep Skull (Borneo) and the Bewah specimen (Malaysian Peninsula). This will provide a better understanding of the settlement of Australia and new knowledge about the ancient people of Australasia and their relationship to other human populations worldwide. The research will use cutting-edge methods of DNA and protein sequencing of ancient human material and will provide critical reference genomes / proteomes that will anchor future research.

Project Ecology of coral reef ecosystems Australian Rivers Institute Coral reefs are complex ecosystems but are under threat from anthropogenic activities. When reefs degrade, corals are normally replaced by macroalgae, therefore understanding macroalgal ecology is critical for the conservation of the Great Barrier Reef (GBR). This project aims at providing fundamental knowledge of the ecological processes involved in macroalgal blooms in the GBR. Oceanography EarthScience	Associate Professor Guillermo Diaz-Pulido
Project Planning for aquaculture expansion under climate change Coastal and Marine Research Centre Aquaculture is one of the fastest growing food sectors in the world, with great potential for expansion. Climate change poses a significant threat to aquaculture production - from potential losses in infrastructure to sub-optimal growth and production rates, but climate change is rarely included in aquaculture development plans. In this project you will work with an interdisciplinary team to assess and incorporate climate risk into aquaculture planning to future proof aquaculture production under a changing climate. Food systems, Climate Change EnvironmentalScience	Dr Caitie Kuempel
Project Quantifying Australian aquaculture's environmental footprint Coastal and Marine Research Centre Aquaculture is a fast growing industry in Australia - which is known for production safe and relatively sustainable seafood products. Australia has great potential for aquaculture expansion but currently has limited knowledge of how aquaculture impacts the environment now and in the future. This project will work to quantify major environmental impacts from Australian aquaculture (nutrient pollution, GHG emissions, etc.) and potential impacts on habitat, species and ecosystem services. The work is essential for sustainable Australian aquaculture and supports many of Australia's Blue Economy initiatives. Conservation, Food systems EnvironmentalScience	Dr Caitie Kuempel
Project Land-based impacts on marine restoration efforts Coastal and Marine Research Centre Land-based run-off is one of the greatest threats to marine ecosystems, following climate change. Marine restoration efforts are ramping up due to global initiatives and local success stories. While restoration is needed, it is also crucial to understand and elimate threats that degraded land and seascapes to begin with. This project will assess the potential risk of land-based run-off of marine restoration and prioritise areas to focus future efforts.

They are also a major focus of international conservation agreements such as the recently adopted Kunming-Montreal Global Biodiversity Framework. This project will use novel methods to quantify human impacts in marine protected areas through time and develop strategies and recommendations to reduce these impacts and improve the effectiveness of marine protected areas. Conservation planning EnvironmentalScience	Dr Caitie Kuempel
Project Land-based run-off in international conservation agreements Coastal and Marine Research Centre Land-based run-off is one of the greatest threats to marine ecosystems, following climate change. However, it is largely ignored in international agreements. Those that do aim to address the issue largley focus on plastics and nutrients but often ignore sediments. This project will explore how international conservation agreements can be better leveraged to reduce all aspects land-based run-off.

Project Cumulative impacts of offshore wind energy production Coastal and Marine Research Centre Offshore wind energy is a promising way to meeting growing energy demand along with carbon emission reduction targets. However, given that the industry is relatively new, there are still many questions to answer regarding it's impact on nature and how to minimise these impacts with smart planning. This project will aim to address these questions to better understand the impacts and environmental thresholds to inform offshore wind development within Australia and globally Conservation planning EnvironmentalScience	Dr Caitie Kuempel
Project Reducing wastewater impacts on nature and people Coastal and Marine Research Centre Nearly 1/3 of coral reefs are threatened by poor qater quality and there are an estimated 800,000 human deaths each year due to sanitaiton-related water pollution. Improved sanitation has the potential to achieve benefits for both nature and people - but is often poorly understood (particularly in communities with little access to resources). This project will asess opportunities for reducing nutrient pollution to achieve both ecosystem and human health objectives - with the potential to incorporate risk and uncertainty from climate impacts.

Project Environmental impact of firefighting chemicals and bushfire leachates on aquatic ecosystems Australian Rivers Institute The project will investigate the fate and effects of firefighting chemicals and bushfire leachates in Eastern Australian waterways to assess the risk they pose to aquatic organisms and ecosystems on the short term and long term. Firefighting chemicals are deployed by emergency services for the protection of life and property, however there is a gap in the knowledge associated with their short- and long-term effects to water quality and aquatic ecosystems. This will be a largely lab-based experimental project and will aim to better understand if and at what scale these chemicals impact aquatic ecosystems and the timescales associated with these potential impacts. Other lines of evidence will also be explored such as the identification of ‘signatures’ associated with firefighting chemicals to better understand the contribution they have to water quality impacts in a large severely burnt catchment. This project is a collaboration between the NSW Government’s Estuaries and Catchment team based in Lidcombe NSW and Griffith University (Gold Coast campus) with opportunities to work across each location. Focus areas are bushfire-related aquatic ecotoxicology, environmental pollution, and environmental chemistry.

Project Discovering macroalgal diversity in the Great Barrier Reef Australian Rivers Institute Macroalgae or seaweeds are a fundamental component of the Great Barrier Reef, but their diversity is poorly known. This project aims at discovering and documenting the diversity of marine benthic algae using molecular methods for a better understanding of their natural history and roles in coral reefs. Oceanography EarthScience	Dr Guillermo Diaz-Pulido
Project Assessing the impacts of chemical pollutants on marine wildlife using novel and ethical techniques Australian Rivers Institute Help us save the sea turtles! Chemical contaminants are accumulating in marine wildlife worldwide. However, due to their large size and often protected status, there are ethical and logistical constraints in conducting traditional whole animal toxicity tests on these animals. Recently, cell-based bioassays have been proposed as an ethical alternative to assessing the effects of contaminants in marine megafauna. This project aims to establish marine wildlife cell cultures and develop species-specific cell-based toxicity bioassays to assess the effects of chemical pollutants in marine wildlife. This project will involve both field and lab components, and include collaborations with state and federal government agencies, non-profit conservation organisations and the private sector Oceanography Environmental Science	Dr Jason van de Merwe
Project Untargeted metabolomics and lipidomics for monitoring environmental health Australian Rivers Institute Advancements in analytical capabilities make it possible to simultaneously measure a comprehensive suite of physiologically important biomolecules in living organisms. These molecules can provide a ‘snapshot’ of the health and general well-being of an organism. This research project aims to establish robust methodologies to make molecular monitoring a reality. The PhD project will apply untargeted metabolomics and lipidomics analysis to evaluate and compare the status of aquatic species from pristine and human-impacted locations, with the goal of establishing biomolecular signatures as indicators of environmental health.

Project Blue-green algae and their toxins - can we manage them in a changing climate? Australian Rivers Institute Blue-green algal blooms dominate many Australian lakes and reservoirs. Toxic species create major problems for drinking water and recreation. We work collaboratively with environmental and water managers to determine the factors controlling these blooms with both field and lab work. Oceanography EarthScience	Professor Michele Burford
Project Is nutrient offsetting a win-win for restoring our rivers and coasts? Australian Rivers Institute Nutrient offsetting provides a market based mechanism for restoring catchments to improve the water quality in rivers and the coasts. Point source polluters pay to restore non-point source pollution in catchments. However, there are significant gaps in knowledge in comparing point and non point sources of nutrients in terms of how they affect the environment. This project will work collaboratively with industry and government to examine these nutrient sources and link them to nutrient responses in the environment. Oceanography EarthScience	Professor Michele Burford
Project Can we use revegetation to control algal blooms? The role of organic matter leached from trees Australian Rivers Institute Our research has found that leaves from trees leach organic matter that can negatively effect algae. However, at the catchment level it is unclear how much impact the organic matter from trees is having on algal blooms. This research would involve working with the water industry to tackle this question. Ecosystem function EarthScience	Professor Michele Burford
Project Automated monitoring of restored marine environments Australian Rivers Institute There is currently a surge in interest in marine and coastal restoration, with a significant number of projects underway, and many more planned. Current methods for monitoring restoration progress and success vary enormously, with low uptake of technological advances that promote efficiency and comprehensiveness. This project will work towards a coordinated, open-science approach to monitoring, that standardises data formats, allows trade-offs or synergies between ecological, socio-economic and cultural benefits to be explored, and facilitates cross-project comparisons and benchmarking. The project takes advantage of Griffith’s leadership in automated monitoring of marine environments, including through computer vision on underwater camera streams. Oceanography EnvironmentalScience	Professor Rod Connolly
Project Ecological connectivity through fish movement measured using artificial intelligence Australian Rivers Institute Connectivity is a guiding principle for conservation planning, but due to challenges in quantifying connectivity, empirical data remain scarce. This project provides solutions to the challenge by using computer vision to automatically extract fish movement data from underwater camera streams. The student will develop expertise in fisheries ecology, statistical modelling and programming. The project takes advantage of Griffith’s leadership in automated monitoring of marine environments, including through computer vision on underwater camera streams. It will lead to better planning and management of marine restoration and protected area projects through incorporation of connectivity principles.

Project Biosolid-based biochars for agricultural carbon sequestration Australian Rivers Institute Biochar is a solid by-product of thermochemical conversion of biomass (in the absence or reduction of oxygen) to bio-oil and syngas, which is dominantly composed of aromatic compounds resistant to biological degradation. Biochar would enhance soil aeration, increase soil pH, favour nitrogen immobilization, interact with available organic C and N in soil, act as an electron shuttle for soil microorganisms and modify soil enzyme activities as well as microbial abundance and community composition. This project aims to investigate how modification of pyrolysis process (i.e., pyrolysis temperature; heating rate; residence time) and co-pyrolysis of biosolid with organic wastes (i.e., feedstock type; blending ratio) would reduce the environmental risks associated with biosolid (i.e., heavy metals; microplastics; PAHs; PFAS), while improve its quality (i.e., C content, specific surface area; porous structure; water holding capacity) for application in agricultural systems.

Project Chlorine Evolution Catalysts for Efferent Seawater Electrolysis Centre for Catalysis and Clean Energy Seawater is the most abundant aqueous resource on earth that is readily accessible at very low costs, but yet to be directly utilised for production of hydrogen fuel and commodity chemicals. This project aims to develop cheap and plentiful carbon-based high performance chlorine evolution electrocatalysts for seawater electrolysis powered by renewable electricity to realise the production of hydrogen, chlorine and sodium hydroxide directly from seawater. The electrolyser can also be used to treat desalination brine while produce hydrogen and chemicals. The success of the project will set a firm technological foundation for seawater utilisation, which will add to Australian capability to meet future energy and environment challenges.

Project Atomically Thin 3d Transition Metal Electrocatalysts for Water Splitting Centre for Catalysis and Clean Energy The current industrial-scale hydrogen productions are reliant on high temperature steam reforming fossil fuels, consuming large quantity of energy and fossil resources, and emitting huge amounts of CO2. This project aims to develop cheap and plentiful transition metal-based high performance water splitting electrocatalysts, enabling economically viable large-scale water electrolytic hydrogen production driven by renewable electricity. A theory-guided catalyst approach will be used to guide the efficient design and development of high performance electrocatalysts. The success of the project will lead to a suit of high performance water splitting electrocatalysts, leaping forward water electrolytic hydrogen production technology.

Project Two-dimensional nanoporous structured high performance gas evolution electrocatalysts Centre for Catalysis and Clean Energy This project aims to develop nano-catalysts with high catalytic activity and rapid gas detachment properties for efficient fuel gas production. Heterogeneous electrocatalytic gas evolution reactions are important for clean energy generation and storage technologies, but high overpotentials caused by slow gaseous products’ detachment from catalyst surface severely hinder their efficiencies. Expected outcomes include insights into gas bubble formation and evolution during electrocatalysis, effective catalyst structures to mitigate negative effects of gas bubble formation, and improved catalytic efficiency of gas evolution reactions and develop high performance electrocatalysts for fuel gas production.

Project Nanoparticle impregnated carbon as a reductive catalysis for environmental toxin removal Centre for Planetary Health and Food Security Nanoparticles have a great potential to be used in water treatment due to its high surface area. This can be utilised efficiently for removing toxic metal ions, microbes and organic matter from water. However, due to their sizes, nanoparticles often form aggregates/agglomerates lowering their activities. To prevent these, further processing including surface passivation is applied. The use of activated carbon into the nanoparticle systems is another strategy as it is simple and economical. Activated carbon was recorded to be used for a multitude of applications, including water filtration/treatment, gas phase adsorption and decolourising agents in the food industry. Research into improving both structure and applications has grown exponentially in recent decades as environmental sustainability has become a key focus, especially the areas involved in environmental remediation. Combination of the nanoparticle and activated carbon provides an excellent platform for the environmental applications such as enhanced capacities and rates. We have developed a system consisting of iron nanoparticles impregnated onto activated carbon. The synthesised materials demonstrated substantially higher arsenic (III) adsorption efficiency/capacity in comparison with nanoparticles and activated carbon alone. The aim of this project is to extend these results producing comprehensive systems for the removal of well-known toxins such as PFAS.

Project Antibiotic-nanoparticle conjugate systems and their effectiveness assessments against gram negative bacteria Centre for Planetary Health and Food Security Antimicrobial therapies have been a magic bullet against infectious diseases since their introduction. However, due to the excessive use of antibiotics via irrelevant and unregulated access, the efficacy of the antibiotic has declined rapidly in parallel with increases in antibiotic resistant bacterial strains. Resistance to this antibiotic has risen rapidly and its clinical usefulness has declined to a point that it is now rarely considered a frontline treatment option. With the emergence of resistant Gram-negative ‘superbugs’, infections caused by multidrug-resistant Gram-negative bacteria have been named as one of the most urgent global health issues due to the lack of effective drugs. Numerous research for new antibiotics focus on developing improved versions of existing molecules, Amongst these new designed and engineered drugs, nanosized particles have gained much recent attention due to their physical size, biocompatibility and functionalities. Nanoparticles are expected to provide a localized cure for complex diseases by facilitating targeted delivery and improved bioavailability. The functionalized nanoparticles can either act as the vehicle for potent drugs or they themselves can act as the therapeutic agents. We have developed antibiotic conjugated carbon-based nanoparticle systems and the conjugated systems displayed notable antibiotic effects on various gram-negative bacteria, including those resistant to the antibiotic moiety conjugated onto the nanoparticle. The aim of this project is to extend these systems to include different antibiotic moieties to construct a range of effective antibiotic conjugate analogues onto the nanoparticles.

Project Quantum observers Centre for Quantum Dynamics Despite its enormous scientific and technological success, quantum theory suffers from deeply puzzling conceptual problems, none more vexing than the quantum measurement problem. It involves inconsistencies that arise when considering the treatment of "observers" as physical systems amenable to a quantum description. Recent results on extended versions of the "Wigner's friend paradox" exemplify the measurement problem in the form of rigorous no-go theorems, such as the "Local Friendliness" no-go theorem. It shows that certain sets of a priori plausible assumptions cannot be simultaneously satisfied by any theory that can accommodate certain phenomena where an "observer" can be treated as ordinary systems subject to quantum-mechanical operations. This project, which has both a conceptual and a technical component, aims to propose increasingly convincing experimental realisations of such phenomena, by asking what are sufficient conditions for a system to be deemed an observer, and what experimentally feasible but increasingly sophisticated quantum systems may provide models of quantum-coherent observers.

Project Quantum causal models Centre for Quantum Dynamics The 2022 Nobel prize in Physics was awarded to the experimental demonstration of quantum entanglement and its counterintuitive properties, in particular the violation of Bell inequalities. A modern way to understand this phenomenon is as a failure of a classical causal model that satisfies relativistic constraints on causal structure. The program of quantum causal models aims at resolving the puzzle of Bell's theorem by extending the classical framework of causality to a quantum setting, while maintaining compatibility with relativistic causal structure. This project will involve further developing the framework of quantum causal models and addressing various open questions, such as counterfactual reasoning, indefinite causal structure, and/or potential applications to quantum information processing tasks. Quantum Physics PhysicalSciences	Associate Professor Eric Cavalcanti
Project Quantum Foundations and Quantum Causality Centre for Quantum Dynamics Quantum technologies are poised to become major drivers of scientific and economic growth in the 21st century. On the other hand, quantum advantage over classical computers has only been demonstrated for a few classes of algorithms. This interdisciplinary project will tackle the key question for unlocking the benefits of quantum information processing: what gives quantum mechanics its information-processing power beyond classical physics? It will explore the hypothesis that quantum advantage is associated to fundamentally different ways in which causality operates in the quantum and classical regimes.

Project Ultra-high-quality generation, communication, and processing of photonic quantum information Centre for Quantum Dynamics Photons are low-noise and flexible quantum systems, perfect for quantum communication and quantum information processing. However, to date, it has not been possible to create key photonic quantum states such as high-fidelity states of many correlated photons and complex heralded entangled photon states. These projects will use high-efficiency photon-pair sources developed at Griffith University and world-leading superconducting photon detectors to develop and generate these important photonic quantum states.

Project Counterfactual quantum smoothing Centre for Quantum Dynamics Quantum state smoothing is a newly developed way to estimate the state of a quantum system at time t using measurement results in both the past and future of t, with applications in experiments with continuous measurements. This project will further develop this formalism, including using it to address the question of what is the most likely thing a quantum system would have done if you had measured it in a different way from how you did. Feel free to contact me about other areas I have published in recently. Quantum Physics PhysicalSciences	Professor Howard Wiseman
Project Quantum machine learning for efficient quantum tracking Centre for Quantum Dynamics The project will apply quantum machine learning to the problem of tracking the state of an open quantum system. Specifically, we want to find the most memory-efficient classical apparatus, which performs adaptive quantum measurements so as to maintain the state of the quantum system in a stochastically varying conditional pure state. While this problem can be attacked by exact methods in classical numerics, these are very computationally expensive, so machine learning is an obvious alternative. Most interestingly is to use genuine quantum machine learning. That is, to perform quantum machine learning experimentally, where the system itself is part of the machine learning loop. This project thus has an experimental quantum photonics supervisor also. Quantum Physics PhysicalSciences	Professor Howard Wiseman
Project Interaction of attosecond light pulses with atoms and molecules Centre for Quantum Dynamics This project is an investigation into the time that it takes for an electron to tunnel-ionise from molecules, referenced to the tunnelling time from atomic hydrogen The proposed research is based around a state-of-the-art laser system, the Australian Attosecond Science Facility (AASF). This laser system is unique in Australia and one of only a few around the world. The light pulses generated by this laser are highly amplified and are only a few cycles of the optical field, and so measured in attoseconds (10-18 sec). We study of the interaction of such strong-field engineered light pulses with matter. The research will build on a ground-breaking research into the time it takes for tunnel ionisation to occur in atomic hydrogen, which was recently published by the Griffith team in Nature [Sainadh et al. Nature, 568, 75 (2019). This project will extend the measurement of the tunnel ionisation of electrons from other atoms and molecules and will provide the most stringent tests to current models for these interactions. Quantum Physics PhysicalSciences	Professor Igor Litvinyuk
Project Continuous beam atom interferometers for quantum enhanced navigation Centre for Quantum Dynamics Atom interferometers have demonstrated great promise for next generation accelerometers and gyroscopes, with significant gains in sensitivity and immunity to bias drift . To date, most work has focused on pulsed atom interferometers, which use a series of time-seaparated light pulses to split and recombine the atomic ensemble, with the resulting phase shif. However, pulsed approaches suffer from significant loss in bandwidth, due to dead-time where no measurement is made. This project will construct a continuous beam interferometer using laser cooled rubidium atoms, with the interfereterometer sequence constructed by atoms traversing spatially separated light fields, giving significant gains in bandwidth and flux.

Project Adaptation of the whale watch industry to climate change Cities Research Institute Globally, the whale watching industry has been increasing in size and economic value since the 1990s. Whale-watching tourism has transformed entire local communities and contributed significantly to economies. The whale-watching industry, and the whales themselves, face uncertain threats from multiple pressures. This includes the impacts of increased sea surface temperature, altered currents and changes in food abundance on whale behaviour. The research project will look at adaptations of the whale watch industry to changing whale distributions and abundance, drawing from two primary species for Australian waters for which the Whales & Climate Program has data on climate change impacts. This study involves modelling, social and economic science, with a focus on sustainable tourism. Eco-Tourism EnvironmentalScience	Dr Olaf Meynecke
Project Whale Economy – the value of whale watching to the Australian blue economy Cities Research Institute Globally, the whale watching industry has been increasing in size and economic value since the 1990s, yet, little is known about the importance of this sector to the local economy. This research project aims to update and establish the latest figures on this sector for Australia recognising the increase of whale watching and swim with whales in Australia. The most recent estimates on the contribution of whale watching to the economy date back to 2008, where it was found that over 1.6 million people went whale watching, generating AUD $47 million in ticket expenditure and AUD $264 million in total tourism expenditure. This project will involve the analysis of historic customer number and revenue data collected by whale watch operators and may also involve collecting data directly from whale watch participants via an expenditure survey.

Project Process-driven sediment regime changes in semi-enclosed tidal estuaries Cities Research Institute The Broadwater on the Gold Coast is a large semi-enclosed tidal estuary that forms the southern portion of Moreton Bay. While the estuary receives fluvial sediments from four major river catchments, the dynamic coastal processes have long dominated sediment inflow into the estuary. The study seeks to quantify the ratio of catchment-derived to marine-derived sediments in the estuary, and determine refined proactive management mechanisms for maintaining ecosystem function and navigability within the estuary.

Project The role of government in sustainable development and addressing climate change Cities Research Institute Governments have a key role to play in achieving sustainable development and addressing climate change. The object of this research is to synthesise policies, plans and strategies that will assist with this transition. While commitments have been made at the international level, and some organisations have made improvements at the local level, there is a strategic gap between the two that has not been fully researched. PhDs can be on either sustainability or climate change and take a theoretical or applied approach. The methods used include case studies, comparative analysis, policy analysis, stakeholder interviews, or surveys.

Project Geochemistry of critical metals in coastal and marine waters Coastal and Marine Research Centre Australia is home to large reserves of "critical minerals" - those metals that are essential to the transition to renewable technologies. Our knowledge of the environmental chemistry of these metals is currently limited, particularly in the coastal and marine waters that will likely be their ultimate sink. This project seeks to use advanced analytical approaches, including Synchrotron-radiation X-ray spectroscopy, to unravel the complex aquatic geochemistry of critical metals in coastal and marine environments.

Project A new therapeutic model for Parkinson's disease: physiological and pathological roles of potassium channels Griffith Institute for Drug Discovery Parkinson's disease (PD) is an ageing-related, multifactorial neurological disorder featuring selective degeneration of dopaminergic neurons in the midbrain. The mechanism underlying the loss of dopaminergic neurons is complex and still elusive. However, ion channels have been shown to play an important role in neurodegeneration due to their fundamental functions in neuronal excitability. In this project, we aim to expand our recent findings on the potential pathological role of potassium channels in Parkinson's disease, and elucidate the underlying molecular mechanisms using a dopaminergic neuron cell model and knockout mouse model.

Project Ameliorating microglia-mediated neuroinflammation for Parkinson's disease therapy Griffith Institute for Drug Discovery Microglial cells, the CNS-resident macrophages, are privileged to be the immune-competent cells of the central nervous system. A large body of evidence supports that microglial cells play a crucial role in mediating neuroinflammation as a significant contributing factor in the progression of ageing-related neurological disorders, including Parkinson's disease (PD). As an essential trigger of abnormal microglial activation, oxidative stress is also a key pathological factor in PD. This project aims to explore how oxidative stress-sensitive ion channels contribute to microglia-mediated neuroinflammation in PD and whether targeting these ion channels may represent a neuroprotective approach to mitigate PD progression.

Project The use of minimally invasive biomarkers in the management of glioblastoma patients Griffith Institute for Drug Discovery Glioblastoma (GBM) is the most frequent and aggressive form of brain cancer in adults. Currently, there are no biomarkers to reliably evaluate disease progression during treatment, leading to delays in important clinical interventions. To improve noninvasive monitoring of cancer and find new potential targets for therapies, liquid biopsy approaches, including the use of extracellular vesicles (EVs), circulating tumour cells (CTCs) and circulating tumour DNA are being investigated. The liquid biopsy approach has advantages over tumour tissue biopsy since it allows serial timepoints collections and in a minimally invasive way. We aim to expand results obtained on EVs, ctDNA and CTCs isolated from blood and saliva of GBM patients, validating them in larger cohorts and identifying novel biomarkers to help in the diagnosis and prognosis of this disease.

Project Precision-engineering of core-shell structures for prevention and treatment of diseases Griffith Institute for Drug Discovery The spread of cancer (metastasis) accounts for 90% of cancer deaths. Critically, this belligerent disease is highly resistant to conventional therapies, and new molecular targets and therapeutic avenues are urgently needed. Professor Richardson discovered innovative anti-cancer drugs that can increase the expression of a metastasis suppressor protein, NDRG1, that prevents tumour cell spread (Fig. 1). He also discovered these same drugs overcome resistance of cancers to chemotherapies by overcoming the drug efflux pump, P-glycoprotein. This project will involve examining the functions of NDRG1 and its targeting by our novel drugs to elucidate the molecular mechanisms involved in their anti-tumour activity. A range of state-of-the-art techniques will be used to maximise student training, including: tissue culture, western blot analysis, immunohistochemistry, medicinal chemistry, and confocal microscopy. Biochemistry Cell Biology BiologicalScience	Professor Des R. Richardson
Project Harnessing the power of the macrophage: innovative anti-cancer drugs known as 'maca-attackers' Griffith Institute for Drug Discovery Despite the massive potential of pharmacologically harnessing the power of the macrophage (MØ), a lack of understanding basic molecular mechanisms led to a distinct absence of MØ-based anti-cancer therapies. MØs are powerful orchestrators of the response to tumours, making up to 50% of tumour mass. The MØ powerfully exerts tumour inhibition via either cytotoxic M1-MØs, or tumour promotion via the M2-MØ phenotype. However, a unifying model of how this occurs via nitric oxide (NO) has never been elucidated. Using our expertise in exploiting transporter pharmacology to develop innovative drugs from bench-to-bedside, we will assess the transporter, multidrug resistance-associated protein 1 (MRP1), to exploit NO transport between MØs and tumour cells (Figure 2) to develop frontier drugs (“MACA-ATTACKERS”) to harness the immense power of the MØ. Biochemistry Cell Biology BiologicalScience	Professor Des R. Richardson
Project Identifying biomarkers for Parkinson’s disease as a step toward a cure Griffith Institute for Drug Discovery Parkinson’s disease (PD) is a complex, incurable, multifactorial neurological condition affecting over 65,000 Australians with an economic burden of $10 billion per annum. With an aging population the disease related costs will rise unless we find better ways to identify those at risk, provide early diagnosis and treat the disease from an understanding of its causation in each individual. The development of robust biomarkers is essential to meeting these challenges. No biomarkers are available which is the major impediment to progress towards a cure. We have developed a cell model of PF using patients’ own cells. Subjecting the cells to chemical stress reveals a different response between cells from PD patients and those from healthy individuals. We have several projects examining how we can use these stress tests to identify the underlying disease trigger in each patient. This is the first step toward personalised medicine for PD. Biochemistry Cell Biology BiologicalScience	Professor George Mellick
Project Exploring new biological targets for treating Parkinson’s disease – from patients back to patients Griffith Institute for Drug Discovery Genetic factors constitute a major component in the aetiology of Parkinson's disease (PD). Significant progress towards understanding the pathologic mechanisms involved in PD and developing new therapeutics has come from studies of rare families with inherited PD. We hold an advantaged position in this research field via access to the unique cohort of thousands of PD patients participating in the Queensland Parkinson’s Project. Through sophisticated genetic studies, we have identified several novel genes from rare PD families, the encoded proteins of which have great potential in elucidating new pathologic mechanisms and providing novel treatment strategies. Using methods in molecular biology, cell biology, biochemistry and stem cell biology, we aim to shed new light on this progressive and devastating disease. Biochemistry Cell Biology BiologicalScience	Professor George Mellick
Project Investigation of cyclization - blocked proguanil analogues for malaria Griffith Institute for Drug Discovery We have made the exciting discovery that the clinically used antimalarial drug proguanil has much more potent activity than previously thought. The activity of proguanil has, up until now, been thought to be due to its in vivo cyclization metabolite cycloguanil, a DHFR inhibitor, and by potentiating atovaquone activity. In this project, cyclization blocked analogues of proguanil, will be investigated as potential new combination partners for atovaquone. Approaches will include in vitro growth inhibition assays, combination studies, time of kill assay and in vivo efficacy testing in murine models of malaria.

Project Developing native mass spectrometry methods to charterise disease related biomolecules Griffith Institute for Drug Discovery This project aims to develop native mass spectrometry methods for characterising challenging and unconventional targets that underpin emerging disease therapeutics. Native mass spectrometry is a rapidly growing biophysical technique – this project is one of few opportunities in Australia to develop skills with this emerging and continually developing methodology. Potential biomolecular targets to be investigated include soluble and membrane proteins and structured RNAs, and their complexes with other proteins, nucleic acids and/or lipid binding partners. Development of these methods will facilitate the fundamental understanding of these molecules and further drug discovery by allowing fragment, or other, screening campaigns to discover novel binding compounds, or characterise previously identified therapeutic binding compounds. This can be applied to various diseases areas including cancer and infectious diseases Chemical Biology ChemicalSciences	Professor Sally-Ann Poulsen
Project Molecular targets program: rapid response to pandemics Griffith Institute for Drug Discovery The Molecular Targets Program identifies ligands for any cloned and purified protein of therapeutic significance. We have developed native Magnetic Resonance Mass Spectrometry (MRMS) to fast track identification of compounds that can be used for therapy.

Project When Glyco meets Nano: Developing novel tools to explore complex glyco-interactions Institute for Glycomics Micro-technologies in the form of Micro-Electro-Mechanical Systems (MEMS) and micro-plasmonics platforms offer the potential for high-resolution, high-throughput label-free sensing of biological and chemical analytes. Silicon carbide (SiC) is an ideal material for augmenting both MEMS and plasmonics routes, however such inorganic surfaces need to appropriately and efficiently functionalised to allow subsequent immobilisation of functional biomolecules. To this end we trialled various organosilane-based self-assembled monolayers for the covalent functionalisation of 2-dimensional SiC films, and have now developed an affordable, facile one-step method. Using high-throughput glycan arrays as our model system a novel platform that has the potential to combine established array technology with the label-free capabilities of MEMS or plasmonic systems is one step closer. Using a similar functionalisation route, we have extended the use of organosilanes to biofunctionalise the surface of 3-dimensional nanoparticles, specifically carbon dots. Carbon dots are cheap, biocompatible, chemically stable, heavy-metal free quantum dots, of low toxicity that offer an alternative approach for bio-imaging and -sensing applications. Again, employing glycans as our model system, we are now using our biofunctionalisation approach to generate glycan-coated carbon dots that we are using to explore complex glyco-interactions.

Project Exploring the immuno-modulatory effect of fungal beta-glucans Institute for Glycomics Mushrooms are increasingly attracting attention for their immuno-modulatory activities, which are primarily due to beta-glucans. beta-Glucans comprise a group of glucose (Glc) polysaccharides that are chemically diverse, with a common b-glucan being cellulose (b-(1,4)-linked Glc. It is non-cellulosic beta-glucans, mainly beta-(1,3)-linked Glc that have been shown to be potent immunological stimulators in humans, and some are now used clinically in China and Japan, as well as being commercially available in Australia. Due to the complexity of beta-glucan chemistry and structure a detailed understanding of the mechanism of action, specifically the structural components that dictate specific immunological responses, are yet to be fully resolved. In collaboration with Integria Healthcare, the overall objective of the project is to explore the immuno-modulatory effects of mushroom beta-glucans, specifically the project aims to structurally characterise commercially available mushroom polysaccharides rich in beta-glucans and correlate this with their associated immuno-modulatory effects The outcomes from this project will lead to a clearer understanding of the properties of beta-glucans associated with commercially available mushroom polysaccharides that induce specific immuno-modulatory effects.

Project Novel agents for anti-fungal drug development Institute for Glycomics The opportunistic human pathogenic fungus Aspergillus fumigatus causes severe systemic infections including Invasive Aspergillosis (IA), a major cause of life-threatening fungal infections in immuno-compromised patients. An over-whelming number of reports appeared in 2020 demonstrating that COVID-19-associated pulmonary Aspergillosis (CAPA) is one of the leading factors affecting morbidity in critically ill COVID-19 patients with some reports even classifying Aspergillosis as a significantly under-recognized ‘Superinfection’ in COVID-19. Drug resistance among fungal pathogens is continuing to develop into an increasingly serious threat to public health and health-care systems worldwide. This PhD projects entails the development of novel antifungal therapies that are urgently needed using our established and unique combined in-silico/SPR drug discovery pipeline evaluating a number of new protein targets.

Project Nanomachineries for Exosomes and Exosomal Biomarkers Analysis Queensland Micro- and Nanotechnology Centre Exosomes are nanoscale (≈30–150 nm) extracellular vesicles of endocytic origin that are shed by most types of cells and circulate in bodily fluids. Exosomes carry a specific composition of proteins, lipids, RNA, and DNA and can work as cargo to transfer this information to recipient cells. Recent studies on exosomes have shown that they play an important role in various biological processes, such as intercellular signaling, coagulation, inflammation, and cellular homeostasis. These functional roles are attributed to their ability to transfer RNA, proteins, enzymes, and lipids, thereby affecting the physiological and pathological conditions in various diseases, including cancer and neurodegenerative, infectious, and autoimmune diseases (e.g., cancer initiation, progression, and metastasis). Due to their unique composition, easy accessibility and capability of representing their parental cells, exosomes, and exosome containing RNAs, proteins draw much attention as promising biomarkers for screening, diagnosis and prognosis of these diseases via non-invasive or minimally invasive procedures. Therefore, isolation and analysis of tumor-derived exosomes and exosome containing biomarkers at the early stage of the diseases could significantly improve the capacity to diagnose the diseases thereby improving outcomes. The Shiddiky group is pursuing studies of the development of multifunctional magnetic nanomaterials based technologies and devices for the highly selective isolation and sensitive detection of exosome and exosomal biomarkers (mRNA, proteins) in patients with cancer and other disease.

Project Point-of-care (POC) diagnostics Queensland Micro- and Nanotechnology Centre The development of an affordable, sensitive, specific, user-friendly, rapid and equipment-free diagnostic method that can detect diseases at the time and place of patient care (i.e., point-of-care) using minimal specialised infrastructure, has the potential to transform health care to many millions people both in the developed and developing countries. Recent advances in sequencing and proteomics technologies have now given rise to a large number of potentially useful genetic, epigenetic and other novel molecular biomarkers for the development of diagnostic methods for many diseases including cancer, infectious and neurodegenerative diseases. Despite these great input from biomedical engineering, significant technical challenges for achieving a functional POC device are yet to be overcome. This is mainly due to the lack of sensitive, specific, rapid and low-cost readout methods. The Shiddiky group is pursuing studies of improving existing and developing entirely new methods that can rapidly detect cancer, infectious and neurodegenerative diseases. Technology, Chemistry, Micro- and Nanotechnology BiologicalScience	Associate Professor Muhammad Shiddiky
Project On-Farm' Devices and Technologies for Broad-Scale Disease Surveillance of Crop Plants Queensland Micro- and Nanotechnology Centre Plant pathogens reduce global crop productivity by up to 40% per annum, causing enormous economic loss and potential environmental effects from chemical management practices. Thus, early diagnosis and quantitation of the causal pathogen species for accurate and timely disease control and management are crucial. Detecting and quantifying pathogen species and their relevant genetic biomarkers in plant extracts at the early stages of the diseases is notoriously difficult to access via conventional methodologies. This is mainly because they are either too slow to enable efficient intervention and application of fungicides (visual observation of symptoms in the field) or are too expensive and technically complex to be used by non-specialized technicians on an industrial scale. The development of an affordable, sensitive, specific, user-friendly, rapid and equipment-free method for broad-scale disease surveillance in crop plants, based on “on-farm” pathogen detection and quantification, is of great interest to the agricultural industry and plant biology. The Shiddiky Laboratory focus to develop portable devices and technologies for ‘on-farm’ analysis of pathogen species and pathogenic biomarkers in unprocessed plant extracts. Such a device would allow more rapid and cost-effective detection, control and management of the plant diseases.

Project Entropy-tuned alloys for hydrogen storage Queensland Micro- and Nanotechnology Centre When metals absorb atomic hydrogen from molecular hydrogen gas, first a disordered solid solution and then an ordered concentrated hydride phase are formed, with evolution of heat (enthalpy). The entropy and enthalpy changes are fundamentally linked through statistical mechanics. The goal of this PhD project is to control the enthalpy of the hydridring reaction by controlling the entropy change, with relevance to hydrogen storage (low enthalpy is desirable) and metal-hydride hydrogen compressors (high enthalpy is desirable). This would desirably involve both theoretical modelling using Density Functional Theory/Calphad to explore the possibilities of designing alloys such that the solid-solution phase has significantly higher/lower configurational entropy than the concentrated hydride phase, and experiments to make small amounts of alloys and measuring their hydrogen uptake properties in the National Hydrogen Materials Reference Facility within QMNC).

Project High-temperature superconductivity in palladium deuteride Queensland Micro- and Nanotechnology Centre Today's room-temperature superconductors are all metallic hydrides. Superconducting transition temperatures (Tc) now reaching, even exceeding, room temperature are however observed only under extreme pressure, above 1 million atmospheres. Palladium hydrides - PdH, PdD and PdT - have been known to superconduct below about 10 kelvin for 50 years. It was recently found that PdH and PdD can become superconducting after absorbing hydrogen at a temperature and pressure above the thermodynamic critical point of the Pd - H2/D2 system, with superconducting transition temperatures reliably reaching 60 kelvin in PdDx (where x is not yet known). While this is low compared to room temperature, only low hydrogen pressures are required. The goal of this PhD project is to conduct cryogenic experiments to measure Tc of PdDx by by means of resistivity and alternating susceptibility simultaneously, under various experimental conditions, and to thereby understand how to obtain the highest possible Tc for this system. Condensed Matter Physics PhysicalSciences	Professor Evan Gray
Project Fundamental thermodynamics of metal - hydrogen systems Queensland Micro- and Nanotechnology Centre Three-quarters of the periodic table is metals, and essentially all of these can be made to absorb hydrogen to form "alloys" (e.g. PdH) and compounds (e.g. MgH2). Thousands of metallic alloys also absorb hydrogen. In very many cases, hydrogen first forms a dilute solid solution which, as the hydrogen gas pressure increases, becomes unstable and a phase transformation to a concentrated hydride phase occurs, up to the thermodynamic critical point of the system. The goal of this PhD project is to investigate some new ideas about hydrogen uptake by metals. Two of these are: (i) Recent theoretical work based on Density Functional Theory proposes that in nanoparticles the system can transform via a single phase even below the critical point. This published result is controversial and has not been proved experimentally. This proposed phenomenon will be investigated in the Pd - D2 system by measuring hydrogen uptake while performing neutron diffraction (at the Australian Neutron Scattering Centre in Sydney) to determine what phases are present. (ii) Recent analysis based on statistical mechanics predicts that the assumed linear relationship between log(absorption pressure) and reciprocal temperature (the van 't Hoff relation) is in fact curved at high pressure, which matters for applications such as hetal-hydride hydrogen compressors for vehicle filling stations. This published result will be tested by measurements of hydrogen uptake by alloys at pressures up to 2000 atmospheres.

Project Modelling and optimisation of hydrogen-based energy systems Queensland Micro- and Nanotechnology Centre The transition to a global energy economy based on renewables is extremely urgent and underway. Hydrogen energy technology has a very imprtant role to play. For instance, it is estimated that the electric power required to produce and export enough hydrogen to satisfy just Japan's needs is more than 1 terrawatt. This compares to Australia's National Electricity Market which peaks at about 30 gigawatts, but also to our readily accessible resource of offshore wind at more than 2 terrawatts. Reliable computer modelling of such energy systems is vitally important in order to know how they will perform before capital investment is made; modelling is much cheaper than building even a pilot-scale system and getting it wrong. The consequences of design mistakes at the gigawatt scale are serious indeed. In this multidisciplinary PhD project, the student will work as part of a team with expertise in physics, mathematics, engineering, energy economics and hydrogen energy technology. The goal is to develop mathematical models and build software to analyse and simulate devices including electrolysers and fuel cells, and to link these into system-wide models for optimising an energy system according to mutually conflicting criteria such as best performance, minimum cost, least environmental harm and acceptable social licence. Optimisation will be by means of bio-inspired algorithms such as Particle Swarm and Grey Wolf. Physics, Mathematics, Computing MathSciences	Professor Evan Gray
Project Simulation of battery electrolytes using artificial intelligence This project combines artificial intelligence with molecular simulation to develop a predictive understanding of electrolyte solutions for developing the next generation of electrolytes for improved battery technology. Electrolyte solutions are one of the most important substances on earth, playing a central role in energy storage, carbon capture and conversion and essentially all of biology. Until recently, however, we have been unable to predict even their most basic properties. Recent advances in the field of AI and molecular simulation mean that for the first time it is possible to accurately predict their properties with existing software. This project will train students in the exciting and rapidly growing area of artificial intelligence for materials science. Many companies including Microsoft, DeepMind, Google Research and Schrodinger are currently investing in this area. physical chemistry, chemical physics, artificial intelligence, materials science ComputationalScience	Dr Timothy Duignan

Project Impacts of disease and environmental contaminants on wildlife conservation Centre for Planetary Health and Food Security Wildlife are in peril due to numerous threatening processes. Amphibians (especially frogs) are the most endangered Class of Veterbrates. Two key threats to amphibians are disease and environmental contaminants. The main disesae of concern is the fungal disease chytridiomycosis (pronounced 'ki-tri-di-o-my-co-sis'). This disease is caused by two related fungi: Batrachochytrium dendrobatidis and B. salamandrivorans. It is the most devastating disease threat to biodiversity ever recorded. To date it has caused the decline and/or extinction of hundreds of frog species around the world. Another key threat to amphibians (and other aquatic fauna) are environmental contaminants (including pesticides, heavy metals, firefighting chemicals, etc.). I have PhD opportunities available to study (1) infection dynamics of chytridiomycosis in frogs, exploring mechanisms of resistance and tolerance to the disease; and (2) independent and interactive effects of multiple threats to frogs, including the disease chytridiomycosis, and environmental contaminants.

Project Cumulative effects of light and chemical pollution on circadian systems in fish Australian Rivers Institute Human activities introduce a huge diversity of pollutants into the environment, often with harmful consequences for wildlife. These pollutants frequently overlap, but many knowledge gaps exist when it comes to predicting their combined risks. Light pollution and pharmaceutical anti-depressants are two of the fasting growing stressors globally and have both been shown to negatively impact aquatic animals, but there has been no research exploring their interactive effects. This project aims to investigate the combined risks of light pollution and anti-depressant pharmaceuticals on the regulation of circadian systems, at multiple levels of biological organisation. The outcomes are expected to yield a new framework for exploring the interactive effects of chemical and non-chemical stressors and to reveal how non-chemical circadian entrainment cues such as light pollution modulate chemical toxicity.

Project Theory of photonic quantum state generation and its use for cybersecurity Centre for Quantum Dynamics In networks with distant parties, light provides an excellent way to transmit quantum information because of its fast propagation and low decoherence. However, these advantages are accompanied by a drawback - the lack of appreciable interactions between photons at the single-photon level, which makes it more challenging to create entangled multi-qubit states with photons compared to other carriers of quantum information. The objective of this theoretical project is to develop optimal state preparation procedures and incorporate them into strategies for showcasing novel quantum cybersecurity protocols.

Project Femtosecond laser irradiation of diamond Centre for Quantum Dynamics This project will explore application of ultrashort femtosecond (fs) laser pulses to process diamond at a nano- and a micro-scale. In an instance when fs laser pulses are focused into the bulk of a diamond crystal or on its surface, the optical power densities exceeding TW/cm2 trigger non-linear processes including simultaneous absorption of multiple photons, leading to multi-photon ionisation followed by avalanche and impact ionisation. This results in a highly localised distribution of optical, electronic and thermal energy within the diamond lattice. Due to ultrashort duration of fs pulses unlike with longer nanosecond and picosecond pulses, the thermal energy has time to dissipate between consecutive pulses rather than accumulate, minimising processes leading to distortion and defects in the lattice. For that reason the fs laser pulses under right conditions can create very precise 2D and 3D structures in the irradiated materials, including diamond, without much damage to the bulk of the crystal. The project will explore a fabrication of 2D and 3D periodic arrays of closely spaced linear and chiral elements in diamond for near-infrared (N-IR) and IR opto-electronic applications. The PhD candidate is expected to optimise the fs-laser facilities for irradiation of diamond and evaluate the properties and performance of fs-laser irradiated structures and features on diamond using a range of optical and spectroscopic methods. This condensed matter/optical physics project will equip the candidate with solid applied skills in laser processing of materials, nano- and micro-fabrication and materials science and engineering skills. condensed matter physics, plasma physics, optical physics, materials science PhysicalSciences	Dr Maksym Rybachuk
Project Diamond-like carbon coatings for engineering and medical device applications Centre for Quantum Dynamics Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of natural diamond. DLC thin-films have been broadly applied in industries owing to their advantageous properties such as high hardness and environmental inertness. In particular, there is a growing demand for DLC use as protective coatings for cutting tools owing to their exceptional wear resistant characteristics, and there is a strong interest for DLC use in prosthetics and ventricular assist devices (i.e., artificial heart devices) owing to their bio-compatibility. The PhD candidate is expected to optimise the DLC coating vacuum process for deposition of hydrogenated DLC coatings on tool steels and titanium alloys and evaluate the DLC coating properties and performance for selected engineering and medical device applications.

Project Reducing freshwater pollution with high-frequency remote nutrients monitoring and machine learning Cities Research Institute Waterway pollution, particularly from agriculture or wastewater, can be significant, and adequate monitoring is vital to understand and minimise environmental and ecological damage. Traditional nutrients monitoring requires manual sampling and costly, time consuming lab analysis; however, new optical monitoring technologies, if properly calibrated, allow the collection of much higher frequency, reliable data. Advances in computational capabilities enable machine learning algorithms to identify patterns and extract knowledge from such large datasets. This project will build on existing research work, making use of available sensors and monitoring stations, to collect large amounts of water quality data, and develop predictive models to understand and manage nutrients concentrations in agricultural waterways.

Project Managing harmful algal bloom with machine learning and optical sensors Cities Research Institute Harmful algal blooms (HABs) are an increasing concern for water utilities and environmental agencies. Their magnitude and frequency has increased in the last years and currently pose a significant risk for water safety and recreational use of waterbodies. Advances in monitoring technology and computational capabilities represent an opportunity to optimise the management of HABs in urban and semi-urban environments. Optical sensors, after specific calibration, allow the quantification in real-time of important proxies for cyanobacteria and total algae, while machine learning techniques enable the extraction of knowledge and identification of patterns from these large datasets. This project is open for a qualified candidate to build on existing research work, encompassing calibration and optimisation of optical sensors employed for HABs monitoring, and development of predictive models to better understand and manage HABs.

Project BIM-DES approach for carbon emission modelling through the life cycle of prefabricated buildings in Australia Cities Research Institute Prefabrication aims to improve the efficiency of the construction processes and quality of the constructed facilities that may lead to substantial greenhouse gas emissions reductions over the life cycle of a building project. Nevertheless, the life cycle impacts of prefabrication building projects have not been adequately recognised in the Australian context. The aim of this research is to present a model to assess the embodied carbon emissions which directly address the inherent dynamics of prefabricated residential projects. The model applies the life cycle assessment (LCA) to calculate the greenhouse gas emissions during the processing, building operation, and eventual demolition, dismantling and disposal phases of a prefabricated building project. The model combines Building Information Modelling (BIM) and Discrete Event Simulation (DES) to create the building data specifications of all processes efficiently.

Project Effects of best practice in program-level planning on the student experience. Cities Research Institute Teaching scholars around the world understand that assessment drives learning (Black & Wiliam, 2009; Boud, 1990; Carless, 2015; Masters, 2014), however there is a lot of variation how academics plan assessment activities (Jessop & Tomas, 2017). Research into best practice for assessment indicates that assessment should be designed to support learning (Baird, Andrich, Hopfenbeck, & Stobart, 2017; Black & Wiliam, 1998; Carless, 2015; Masters, 2014; Weir, 2020). However, the modular approach to assessment within degree planning presents difficulties that students experience in learning from their assessments (Eva et al., 2016; Jessop & Tomas, 2017; Tomas & Jessop, 2019). Academics primarily responsible for learning and teaching need to comply with Federal and institutional policy, and therefore need to ensure the programs they manage or teach into are of a high standard to produce work ready graduates (Medland, 2016; Panigrahi et al., 2015). There are existing gaps in the literature that present practical guidance for academic staff responsible with planning a program of study and policy directives to facilitate this process. Insight into current policies in Australian universities and how these are currently being implemented will provide insights into program level assessment planning and the constraints and enablers to this process.

Project An Industrial Design Investigation into the Sensory Needs of Children with ASD Cities Research Institute This research project aims to create a sensory design framework for the needs of children on the autism spectrum. Due to the sensory abnormalities these children experience, their engagement with objects and environments can be limiting and cause distress to and disrupt their daily lives. The design framework aims to assist and guide design choices when it comes to material, form and colour decisions when creating devices for children on the autism spectrum. There is no current design framework or guide for these children as their sensory needs are so varied. To try and cater to all the anticipated needs, a multitude of aspects will be investigated to describe each material choice Industrial Design BuiltEnvironment	Professor Caryl Bosman

Project Progressive Collapse Resistance of RC Flat Plate Substructures under Column Removal and Slab-Column Joint Damage Scenarios Cities Research Institute This project covers comprehensive experimental, numerical and theoretical studies of RC flat plate structures in the context of progressive collapse. Three experimental tests were conducted on 1/3-scaled 2×2-bay RC flat plate substructures with 8 or 9 columns. Following the alternative load path (ALP) method, the first test (i.e., 8-column dynamic test) was carried out to investigate the dynamic responses of the substructure during the flexural, punching and post-punching stages by instantaneously removing the interior column and under three incremental levels of gravity loads. The second and third tests (i.e., 9-column static and dynamic tests) were performed, under static and dynamic loading scenarios respectively, on the intact specimens without removing any column. Numerically, a set of high fidelity finite element models was developed to replicate the structural behaviours of tested substructure specimens, and accordingly the Dynamic Increase Factors (DIFs) of both 8- and 9-column specimens were determined. Furthermore, the flexural capacity of the 9-column static test on the intact specimen was predicted theoretically based on the observed yield line patterns.

Project Progressive collapse resistance of Reinforced Concrete Flat Plate Structures Using Prestress Technique Cities Research Institute This project consists of experimental and numerical studies of the strengthening methods for flat plate structures against progressive collapse. The strengthening methods include “hidden beams”, “ring beams”, “stirrups in punching area” and “post-tensioned prestressed concrete slabs”. The focus is post-tensioned prestressed concrete flat plate structures and a series of slab-column joint tests will be conducted. 3D high fidelity finite element models will also be developed and calibrated with the experimental results. Furthermore, a comprehensive parametric study will be conducted to expand the scope of the experimental studies to cover a wider range of design parameters (e.g. slab thickness, level of prestressing forces, arrangement of prestressed tendons).

Project Post-tensioned flat plate system with high strength fibre reinforced concrete (HPFRC) shear head for progressive collapse prevention Cities Research Institute This study is to develop a new post-tensioned concrete (PTC) flat plate system using high-performance fibre reinforced concrete (HPFRC) for the shear head, which is particularly useful for strengthening the punching prone regions. Post-tensioned prestressing tendons will provide an effective alternate load path in the system, as well as to reduce the amount of steel and concrete usage and the slab thickness. A series of material characterisation and testing programs will be conducted to evaluate the performance of HPFRC with fibers and to determine a desirable balance between the proportion of fibre reinforcement and the concrete strength that could produce desired strength of HPFRC. Subsequently, a series of scaled down slab-column connection specimens will be tested. The strength and the size of shear head will be varied to examine the potential punching shear failure which may occur in different conditions, such as failure happening inside the shear head, outside the shear head, or in both regions. Further, a high-fidelity finite element modelling framework for the proposed PTC system will be developed and validated against the experimental results. Through numerical analysis, the nonlinear behaviour, load transfer mechanisms, and damage modes of slab-column connections under realistic progressive collapse scenarios will be captured. Finally, numerical parametric studies will be performed to study the effects of the strength and size of the shear head, and the slab lateral restraints on the punching shear and post-punching capacities.

Project Model Updating of a Cable-Stayed Bridge Using Structural Health Monitoring Data Cities Research Institute One of the many challenges of managing cable-stayed bridges is the development of numerical models that can accurately assess dynamic characteristics, such as modal frequencies, mode shapes, and modal damping values of these highly redundant systems. Ongoing developments in sensor and data acquisition technologies have made it possible to install extensive structural health monitoring (SHM) systems on many new and existing bridges which affords the opportunity to validate and update models of these structures. While most bridge-SHM studies published focus on finite element (FE) model validation, very few use updated models to further investigate the condition of critical structural components. Furthermore, the challenges of considering the inherent uncertainties in model updating of long-span bridges are often ignored. Using an in-service case study bridge fitted with an SHM system, this research project proposes to create and update an initial FE model of a cable-stayed bridge, and use this model to evaluate the condition of the stay cables through natural frequencies and cable tension as part of the bridge’s overall SHM efforts. A Bayesian approach to model updating will be considered to account for uncertainties. Structural engineering, structural health monitoring, bridges BuiltEnvironment	Professor Hong Guan
Project Spatial MCDM tool for offshore wind and solar energy systems Cities Research Institute Implementing offshore hybrid renewable energy systems have strong potential to accelerate our transition to a net-zero economy. However, there is a lack of a systemic and autonomous spatial approach to evaluate the potential sites for coupled wind and solar, considering multi-criteria covering environmental, technical, economic and social aspects. The main objectives of this study are: (1) To determine the energy mix scenario for offshore wind farm and solar power plants considering the energy demand in Australia; (2) To develop a tool to autonomously identify optimal site locations for offshore wind and solar plants considering both environmental and social constraints/impacts as well as energy demand; and (3) To develop an interactive spatial heat map of potential optimal locations. The Multi Criteria Decision Making (MCDM) approach will be applied to consider economic, technical, social, and environmental aspects. MCDM methods have become popular for the assessment of renewable energy resources due to consideration of preferences of decision makers and various conflicting criteria. Moreover, the project will create a spatial data platform that autonomously collects and dynamically analyses various datasets using statistical and MCDM methods. The platform will include a user-friendly GIS-based visualisation module that displays suitable locations for offshore renewable energy systems to decision-makers. The developed tool will be validated for the Australian coastal context but will be designed so that it is generalisable worldwide in order that is has far reaching application.

Project Novel development of a data-driven assessment tool for recycled wastes in construction using hybrid life-cycle framework and artificial intelligence methods Cities Research Institute In this project, the classical 5-stage life cycle assessment (LCA) of a variety of common by-products or wastes suitable for construction use shall be carried out. Mining by-products (e.g. fly-ash, slag and red mud) and landfill wastes (e.g. plastic, construction and demolition wastes) are considered recyclable or reusable materials due to their inert but ‘attractive’ physico-chemical properties that would require deliberate and specific ‘activation’ processes. Combining the LCA framework with the powerful big data analytics driven by artificial intelligence Bayesian Inference method, a trainable, updatable and reliable predictive model can be developed to optimise the life cycle of each of the reclaimable waste when it is used in a typical construction project. For example, fly-ash is a by-product of coal combustion and once it is chemically-activated (called geopolymer or ‘green cement’), it has superior mechanical properties than the environment-polluting cement.

Project Lubrication effects on pipe surface roughness in pipe jacking operations Cities Research Institute Pipe jacking technology is becoming more popular in urbanised areas because it is environmentally friendly and cost-effective. This technology is an excellent alternative to open-trench methods for pipeline construction. To explore the soil-pile interface behaviour in laboratory tests, the Direct Interface Shear test machine is modified to receive a split-window loading ram on a fully-automated loading and shearing system and a purpose-built transparent shear box. This is then followed by using actual concrete surfaces to mimic the surface finish of different types of pile foundations (e.g. pre-cast vs cast in-situ). Based on Particle Image Velocimetry (PIV) of discrete element method (DEM) technology applied to the Direct Interface Shear test adopting the transparent shear box, the shear failure (sliding) mode at the pile-soil interface can be clearly distinguished through the reliable digital visualisation technique, thus tracking the movements of granular particulate behaviour from start to finish so as develop greater understanding on the corresponding plane-stress, stress-strain relationship.

Project Strength and Microstructural Assessment of Reconstituted and Stabilised Dredged Mud with Varying Silt and Water Contents Cities Research Institute The study of the strength of reconstituted and stabilised soft soils such as dredged mud off Brisbane River is very important in geotechnical engineering. The soil particles such as clay, sand, and silt play important roles in determining the behaviour of soils. The behaviour of clay and sand particles are unique; however, the behaviour of silt particles lie in a transitional form between sand and clay. Therefore, this project seeks to investigate a) the effect of silt contents on the strength of soft soils; b) the effect of silt content on the strength of cement-stabilised soft soils; and c) the microstructure and performance of the soft soil specimens stabilised by cement and/or additives as a form of sustainable ground improvement methods.

Project Optimizing Submerged Breakwaters for Coastal Protection Coastal and Marine Research Centre Our study proposes a hybrid model using computer simulations of submerged breakwaters to generate data for a data-driven system that optimizes the structural design given the coastal environmental conditions. Due to the complex interaction of environmental and design variables, the study of submerged breakwaters are expensive and time-consuming. While there are multitudes of benefits, such as surfing and diving amenity, the influence of submerged breakwaters on the shoreline must be understood to implement a project.

Project Artificial intelligence assisted resilient operation of energy systems Institute for Integrated and Intelligent Systems Renewable energy-integrated systems are very complex to analyse and control since more uncertainty is introduced into the energy system operation, which pushes them to their operational limits and more nonlinear and complex behaviour. This makes the security assessment of the energy system a central tool to predict and mitigate risks for partial or total blackouts. Due to the size of the problem of assessing energy system security, the computational complexity makes it impossible to evaluate all possible operating points for systems with more than a few tens of nodes. The goal of this project is to propose an algorithm that improves the accuracy of prediction of energy system security through AI-based simulations, which leads to more resilient electric power networks.

Project Automatic segmention and classification of paediatric swallowing sounds Institute for Integrated and Intelligent Systems This project aims to investigate and develop an automatic segmentation algorithm that determines the start and stop times of swallowing events from audio recordings of babies and pre-term neonates. Currently, swallowing events are manually segmented by clinicians, so it would be of great benefit for a computer to automatically do the segmentation. Once segmented, the next task is to investigate machine learning algorithms to classify whether these swallows are normal or aspirating. Knowledge of theory and implementation in signal processing, speech processing, machine learning, deep learning methods, and Python programming is preferable. signal processing, machine learning, artificial intelligence Engineering	Dr Stephen So
Project Optimizing target weights and product aesthetic for packing fruit Institute for Integrated and Intelligent Systems When fruit is packed by human packers they tend to pack excess fruit to speed the packing process which means that farmers suffer significant losses through this “give-away” of fruit. During the fruit packing process, there is a standard punnet weight, packers are expected to pack to this exact weight per say. However, in practice, excessive fruit is frequently packed, especially by inexperienced packers, which incurs significant loss to farmers in the form of “give-away” fruit. The project will investigate how packers pack fruit and in particular it will investigate how a machine learning model that monitors packer’s packing behaviour and adjusts the target pack weight can be used to reduce fruit “give-away” thus reducing loss to farmers. Another point of investigation is the aesthetic beauty of packing, so the punnet appears to be attractive to customers, this requires the packer to have jigsaw puzzle solving skills for packing eye-pleasing punnets with fruits of various sizes distributed symmetrically. The project will also investigate ways of eye-pleasing packing patterns and propose attractive fruit distribution schemes that promote product sales.

Project Using deep learning for imag-based plant disease detection and classification Institute for Integrated and Intelligent Systems Plant diseases (e.g., crop and cotton) are a major threat to food security and industrial production, but their rapid identification remains difficult in many parts of the world due to the lack of the necessary infrastructure. Furthermore, there exist different types of plant diseases, it is necessary to classify them effectively. The problem of detecting and classifying image-based plant disease has attracted a lot of attention from researchers. However, there are still many challenges in accurately and efficiently identifying and classifying plant diseases, e.g., how to effectively identify and classify plant diseases under extremely limited sample conditions. This PhD project aim to develop novel deep learning techniques for solving the problem. Machine learning, AI Geometric Aesthetic EnvironmentalScience	Professor Yongsheng Gao

Project Re-Bordering: The Border as an Apparatus for Interaction between Refugee and Host Communities. An Australian Experiment School of Engineering and Built Environment Borders are ubiquitous and multifaceted constructs of contemporary existence that are increasingly used as devices of separation and control. This research seeks to subvert the dividing connotations of the border via the architectural process of Re-Bordering, a newfound theory whereby existing borders are reconstructed into zones of interaction and exchange. Re-Bordering stems from the theoretical distinctions between the border and boundary established by Stephen Gould (Ecologist) and Richard Sennett (Sociologist). In this study, the application of Re-Bordering focuses on softening the border/s between host and refugee communities. Re-Bordering is, therefore, positioned as an apparatus for interaction, connection and exchange between refugee and host communities. Re-Bordering aims to establish a sense of belonging, mitigate against discriminatory attitudes and widen social networks for refugee populations. The promise of increased community connectedness facilitated through Re-Bordering benefits the host community by promoting more permeable, adaptive, and resilient communities. The study adopts a Research by Practice methodology that is central to developing, testing, and understanding the concept of Re-Bordering from an architectural perspective.

Project SiC-based Power Switches for Efficient Systems Queensland Micro- and Nanotechnology Centre Investigating efficient conversion of electrical energy beyond the limits of silicon-based technology. Increasing demand for efficient conversion of electrical energy has motivated research and development beyond the limits of the well-established silicon-based technology. The dominant control switch in electronics is the metal–oxide–semiconductor field-effect transistor (MOSFET), which complements diodes in power-electronics systems. Silicon carbide (SiC) MOSFETs enable improved power efficiency and increased switching frequency, which in combination with SiC Schottky diodes reduces the size of power systems. Both SiC Schottky diodes and MOSFETs can operate at much higher temperatures than silicon devices, which enables applications not possible with silicon power systems. This is especially important in applications for solar inverters and car electronics. Micro- and Nanotechnology Technology	Professor Sima Dimitrijev

Project Climate change impacts on wave-driven longshore sediment transport-projection and uncertainty analysis Cities Research Institute Beach-dune systems can act as natural barriers to protect coastal regions from inundation by storm surge and wave action and are also important ecosystems providing natural habitats for various animals and plants. Sandy beach-dune systems evolve under the influence of a complex combination of hydro- and morpho-dynamics coastal processes across a wide range of spatio-temporal scales. Over decadal timescales the effect of longshore sediment transport (LST) processes on coastal evolution is evident. However, hindcasting or projecting future patterns of LST patterns, itself, is really challenging due to the uncertainties arising from different sources. Due to climate change (CC) impacts on atmospheric circulation, global and regional wave climates of many coastal regions around the world might change. As the wave parameters control the wave energy flux; any changes in these parameters could result in significant changes in patterns of coastal sediment transport and resulting coastal evolution. It should be noted that the effect of changes in the LST patterns on coastal evolution can be comparable to or greater than the impact of sea level rise (SLR). Although the impacts of global CC specifically on LST patterns, have been studied for some cases around the world, the reliability of their projections is questionable as they poorly addressed uncertainty evolution in the projections. Sampling uncertainties, at least from the main sources including emission scenarios, wave forcings, and sediment transport models needs to be considered. In this way, the level of confidence and robustness of the projections can be determined. Moreover, finding the contribution of each source of uncertainty to total uncertainty is a vital step towards reducing uncertainty ranges in the projections. In light of the above, the present research work aims to study the climate change impacts on wave driven LST patterns, and to provide insight on uncertainty evolution in the LST projections. For this purpose, first, a comprehensive literature review was conducted to identify the gaps, and to clearly define research aims. Then, three phases (one for hindcasting and two for projecting LST patterns) were considered. Seven sites along a non-straight coastline (Gold Coast, Australia as the case study) were selected to conduct the required experiments for each phase of this research.

Project Low-power long-range (LoRa) wireless sensor network for smart cities. Queensland Micro- and Nanotechnology Centre Wireless sensor network offers a more cost-effective, accurate and faster Internet of Things (IoTs) solution compared to traditional technologies, which require excessive labour and maintenance costs. This project will develop a wireless sensor network for smart cities utilizing the low-power long-range wide-area network (LoRaWAN) technology. Unlike wired sensor network, it can significantly reduce energy consumption and lower the development and maintenance costs. The raw real-time data will be processed locally at the sensor node and the meaningful data will be transferred wirelessly to the gateway more than 3 km away. The long distance can dramatically reduce the quantity needed for the sensor nodes, thereby covering much larger areas to be monitored. The gateway can then send the data to the Cloud for analysis and forecasting to build an early warning system based on artificial intelligence.

Project Enacting 'procedures as resources for action' approach through new technology and IT system Institute for Integrated and Intelligent Systems High risk industries reliance on procedures is high; there are checklists, memory items, procedures, manuals and rules that direct how a cockpit should be configured, what to do in an emergency and whether an aircraft can take off given the physical environmental conditions. Despite their relevance, the number of procedures and rules is increasing every year without a direct translation into a reduction in the number of accidents and incidents. As an alternative to the current approach to procedures, which are seen as the only way to create safety, resources for action see procedures as a supplement to the activity. It provides the information required to complete a task if and when the worker needs it. However, how do procedures as resources for action look like in practice? In this research project, we aim to develop normal and abnormal situations checklists sensible to the context that provide the information needed, when needed, if needed.

Project Reinforced Thermoplastic Pipelines for transport of Hydrogen. Cities Research Institute Hydrogen is becoming popular as a sustainable source of energy globally. The Australian government is currently funding millions of dollars in multiple projects to promote usage of Hydrogen. According to the Low Emissions Technology Statement of the Department of Industry, Science and Resources (DISR), Australia aims to reduce costs and develop innovative technologies to meet the government’s goal of hydrogen production under $2/kg. Current pipeline infrastructure, which is mainly designed for transporting natural gas, has several limitations for hydrogen transport, such as: embrittlement and cracking of steel pipelines, performance evaluation and performance testing. Reinforced thermoplastic pipe (RTP) can be a solution due to its high chemical resistance, durability, flexibility and cost-effectiveness. The aim of this study is to provide recommendations for design of RTPs with variable fibre thicknesses and fibre orientations under different internal pressures. The proposed RTP consists of an inner high-density polyethylene (HDPE) pipe reinforced by glass fibre wrapping (GFRP), and then inserted into an outer HDPE pipe.

Project Safety Management Systems Differently: developing tools for safety practitioners of the new era Institute for Integrated and Intelligent Systems Safety management systems are a reality and a requirement in many industries, from aviation and healthcare, to oil and gas and constructions. Also known as Occupational Health and Safety (OHS) System, Health, Safety and Enviroment (HSE) Systems, these systems have not been able to improve the safety records as expected and the limitation pointed out by many scholars is the reliance on outdated assumptions and limited evidence. Considering new approaches to safety management, such as safety-II, safety differently, resilience engineering, and other, this research project aims to analyse the limitations of safety management practices commonly employed by safety management sytsems and update or develop new practices. The ultimate goal is to help industry make their SMS more effective. OHS Management	Dr Guido Carim Junior
Project The rational use of simulators and training devices for training in transport industries Institute for Integrated and Intelligent Systems Simulators and training devices are applied in a range of educational settings. From vocational and tertiary degree to high risk industries, these educational technologies are engaging, they place students at the centre of the learning process, force students to be active and serve as a great risk-free enviroment for safety critical training. Despite being extensively used for trianing operators in aviation, maritime and rail, there is still a perception that high fidelity simulators are always a preferred technology. The assumtion is the similar to a real enviroment, the better. However, recent research has shown that simulators and training devices will never fully reproduce reality and the low fidelity ones are as helpful if employed with appropriate pedagogy and support materials. In this research project, the objective is to assess how different simulator and training device tehnologies can employed to enhance training. Which tasks and skills can be developed accross a range of devices taking into consideration learning objectives, training outcome, quality, length and costs?

Project Structura Behaviour of Aluminium Sub-Heads in Façade Systems Cities Research Institute A window wall is a lightweight external wall composed of glass and aluminium, which does not carry any gravity loads from the building, except for its own weight. The wind load applied to this façade system is transferred to the main structural system through the connections of sub-frames (consisting of sub-heads and sub-sills) with slabs. The aluminium sub-head flange due to its long length is susceptible to bearing failure under this loading condition, a phenomenon that has not been adequately researched yet. This PhD project investigates the bearing behaviour and design of aluminium sub-heads through comprehensive experimental testing and advanced numerical modelling.

Project Runway Grooving Techniques and Deterioration Model The friction of runway pavement is critical for the safety of aircraft landing and movement on the runway. Tire hydroplaning may lead the aircraft to move off the runway and hinder the safe landing during wet weather conditions. Grooving on the runway is one way to develop frictional braking resistance and diminish hydroplaning's potential risk by improving runway surface drainage capacity during damp weather. According to the Federal Aviation Administration (FAA), groove construction must follow specific dimensions to maintain skid-resistant airport pavement surfaces. However, the groove area can be reduced for several reasons, and regrooving is essential if 40% of the runway groove of a substantial length decreased to 50% of its original dimension. Grooves initiate different potential distress mechanisms that are not found in an ungrooved pavement surface. Pavement Engineering	Associate Professor Erwin Oh
Project Assessing Airport Pavements Using FWD/HWD Test Airport pavements are widely constructed as airport runways, taxiways, and aprons. The airport traffic should be considered during the design stage of airport pavements before the construction. To protect airport pavements from negligent overload, a pavement strength rating system and an aircraft load classification system are adopted. Under the rating systems developed by the International Civil Aviation Organization (ICAO), Aircraft Classification Number (ACN) and Pavement Classification Number (PCN) are calculated to assess the aircraft loads and the load-carrying capacity of the airport pavements for unrestricted operations. With the increase in the air transport demand, increasing attention on the continuous evaluation of airport pavement conditions is introduced to airports across the globe.

Project Novel methods for modelling road freight in Australian cities Cities Research Institute The Commonwealth has forecast Australia’s urban freight volumes to grow by over 50 per cent from 2020 – 2040, with increases in both urban and inter-urban road freight. Truck fleets will be converted to emissions-free and more automated driving technologies, dramatically improving sustainability, safety and amenity. But with limited capacity to increase road space, making more efficient use of existing arterial networks is essential for Australia’s cities and ports. New datasets are being developed such as the Prototype National Freight Data Hub; machine learning techniques and video data feeds provide other opportunities to collect freight data. This project works with transport modellers and experts in urban road infrastructure to help create and test advanced methods and new models for road freight planning, and to use these to evaluate different ways to try and meet, or better manage, urban travel demand.

Project When, where and why should we use truck lanes and truckways in Australian Cities? Cities Research Institute Australia’s national highway system, and especially its urban arterial roads and connections to urban ports, are often struggling to maintain reliable access for freight movement, despite the higher-value of freight movements to the economy. Truck lanes on arterials, freight bypasses, and dedicated truckways to key industrial and port zones, can increase the efficiency and sustainability of the transport system, and reduce truck movements on inappropriate routes through sensitive urban neighbourhoods. Truck lanes can also improve non-freight operations, such as public transport services in the same corridor. This project takes a novel approach to freight planning, using new transport and land use datasets now emerging in Australian cities. The PhD candidate will work in conjunction with a major road operator to identify and test a series of truck priority measures, from time-limited and temporary truck priority measures, through to full dedicated truck lanes and truckways, that could improve system efficiency and improve urban amenity. Suitable PhD candidates with the following background: a disciplinary background such as transport engineering, planning, economics or urban spatial analysis, with a preference for candidates with skills in Python coding, R software, geographic information systems, and/or 4-step modelling software.

Project Inclusive transport for Australian cities Cities Research Institute Project Summary: It is essential that people have access to the jobs, education, goods and services they need in daily life. But many in society have less opportunity to use our transport systems. 4.4 million Australians live with a disability and transport is fundamental to their independence. The Queensland Government has the laudable aim of trying to create “an integrated transport network that is accessible to everyone”. That means being accessible and inclusive across public transport, active transport, and other modes, both within our cities and towns, and between them. Recent studies have helped identify areas for research focus, to help policies and programs make a difference. Inter-disciplinary research teams are being formed to help increase people’s independence through improvements to the built environment, transport systems, policies and funding arrangements. This project will be tailored to the particular skillsets of the candidate, to focus on a key issue for inclusive transport in the Queensland/Australian context. The PhD may include investigations into: better journey planning and information; community transport services; use of and interactions with new modes (i.e. e-scooters); personal safety and security issues; inclusive design of vehicles and stops; affordability; administrative burdens; and/or welfare outcomes. The project will work with and through local disability community advocacy groups. Suitable PhD candidates with the following background: a disciplinary background such as transport engineering, planning, economics or urban spatial analysis. Useful skills would include qualitative skills such as social surveys, interviews and focus groups; policy analysis; and more quantitative skills such as economic analyses; statistical software (i.e. R); and, geographic information systems. We are especially keen to hear from possible candidates who themselves have a disability. Research Environment: Griffith’s transport research team is highly ranked internationally, has an enviable peer-support program involving staff and PhD students, and is housed in one of Griffith’s premier buildings (the very accessible Sir Samuel Griffith Centre).

Project Tactics for Retrofitting Suburbia: Architects as Critical Actors of Change Cities Research Institute Recent literature and built projects have taught us that creating better suburbs is the key to better cities. Methods and approaches for reinvigorating suburbia abound. However, the importance of the architect’s roles and activities as an individual actor within the regulatory environment of suburbia has been widely underestimated. This is particularly the case in the context of Australian suburbs, where architects have critically contributed to enhancing its built environment throughout history. The PhD candidate would explore the significant impact of architecture as a catalyst for change in creating socio-culturally meaningful and environmentally sustainable suburbia. The candidate is expected to have an architectural design background and might need to contribute to design projects on reinvigorating suburbia.

Project ML-Enhanced Constitutive Material Modelling of Auxetic Composites Cities Research Institute Auxetic structures are gaining attention for their adjustable properties in varying conditions, serving as a core in sandwich structures to mitigate energy transfer during impact, shock loading, crushing, and bending. These structures, conducive to personal protection equipment and protective constructs, are being developed using modern additive manufacturing. The project aims to create efficient sandwich composite with an auxetic core through novel designs, optimizing their performance using finite element and Machine Learning based tools. Numerical modelling of 3D printed parts will involve establishing a constitutive relationship implemented in ABAQUS, considering material properties at different strain rates and temperatures to enhance the efficiency of the material model. This approach enhances load-bearing capabilities and provides a predictive tool for future researchers analysing the material response of additively manufactured components.

Project Vibration characteristics of auxetic sandwich panels Cities Research Institute In the recent years, auxetic materials have received a great deal of attention due to their unique performance characteristics under mechanical loading. Their exotic behaviour is attributed to the negative values of Poisson's ratio where a longitudinal compression (tension) is accompanied by a transverse shrinkage (expansion). In the classical theory of elasticity, Poisson's ratio ranges between −1 and 0.5 for isotropic media whereas for the anisotropic continua, there are no limits for its values. Such a vast design space offers opportunities for improved dynamic characteristics. This project aims to suggest an improved design for the core layer of the sandwich structure, taking advantage of auxtic behaviour. Finite element simulation and/or continuum mechanical modelling will be used with a possibility of incorporating physics-informed machine learning techniques.

Project Gender equality in Aviation - From academia to industry boards GIFT The aviation industry is often seen as a symbol of globalisation, connecting people and businesses worldwide. However, despite its global reach, the industry has been slow to address issues of gender inequality. Women have been historically underrepresented in aviation, from academia to industry boards. This has led to a lack of diversity in leadership positions and a culture that can be unwelcoming to women. In recent years, there has been a growing recognition of the importance of gender equality in aviation. From initiatives to increase the number of women in pilot training programs to campaigns to promote diversity in leadership roles, the industry is taking steps to create a more inclusive environment. Despite the progress that has been made, there is still a long way to go to achieve gender equality in aviation. By continuing to push for change and challenging the status quo, this research aims to explore avenues that will lead to a more inclusive future for aviation.

Project Automated cyber threat hunting using NLP Institute for Integrated and Intelligent Systems Advanced cyberattacks pursue their victims over months or years until they can reach their final goal. Detecting these threats in early phases before the final stage of attacks can be executed against endpoint devices can help prevent adversaries from achieving their goals. Many organisations use cyber threat hunting to proactively detect hidden intrusions before they cause a major breach. The goal of hunting is detecting threat actors early in the cyber kill chain by searching for signs of an intrusion and then, providing hunting strategies for future use. An emerging method in cyber threat hunting is using Natural Language Processing (NLP) methods to automate the hunting process. This project aims to investigate and develop practical threat hunting approaches using NLP methods. This method can be used to automate the extraction of indicators of compromise (IoCs).

Project Adversarial Attacks on Machine Learning-Based Models in Cybersecurity of Cyber-physical systems Institute for Integrated and Intelligent Systems Modern Intrusion Detection Systems (IDSs) rely on machine learning for detecting and defending cyber-attacks in information technology (IT) networks. However, the introduction of such systems has introduced an additional attack dimension; the trained IDS models may also be subject to attacks. The act of deploying attacks towards machine learning-based systems is known as Adversarial Machine Learning (AML). The aim is to exploit the weaknesses of the pre-trained model which has “blind spots” between data points it has seen during training. More specifically, by automatically introducing slight perturbations to the unseen data points the model may cross a decision boundary and classify the data as a different class. As a result, the model’s effectiveness can be reduced as it is presented with unseen data points that it cannot associate target values to, subsequently increasing the number of misclassifications. Adversarial machine learning attacks and automated detection of these attacks in computer networks will be investigated in this project. This project aims to investigate adversarial attacks to machine learning in cybersecurity of cyber-physical systems and propose mitigation techniques to defend against these attacks.

Project Generating and sharing cyber threat intelligence in industrial control systems Institute for Integrated and Intelligent Systems Cyber threat intelligence (CTI) is the knowledge about a threat, and it includes threat indicators such as Tactics, Techniques, and Procedures (TTPs), IPs, etc. CTI can help organizations to learn about existing threats. Cyber threat intelligence can be received from external open-source threat intelligence, or it can be extracted from adversarial activities in organizations’ networks. The CTI generated will be used to build intelligence about threats against a given target. In cyber threat intelligence, indicators of compromises (IoCs) are generated. These IoCs of the detected adversary can be processed and distributed. Security analysts to use CTI information from other companies and share back their IoCs with other trusted partners. These shared IoCs can be used to update detection rules and blacklists in security devices like firewalls. This project will review state-of-the-art techniques CTI sharing and identify gaps in the current solutions.

Project New intelligent and human-centred approaches to supporting airline pilots’ decision making in complex situations to improve flight safety Institute for Integrated and Intelligent Systems One of the greatest challenges to airline flight safety, is how well the pilots diagnose and respond to complex abnormal or emergency situations, such as multiple failures, false alarms, and inoperative systems, which can arise during flight of modern aircraft. Aircraft have evolved to become technically highly sophisticated, becoming more ‘robot than machine’, but approaches to pilot support in the modern cockpit lag well behind. Pilot support in the cockpit remains limited to traditional approaches (the checklists and procedures of the Quick Reference Handbook), effectively leaving pilots unsupported, 'mostly on their own’ to deal with complex, safety critical situations. The aim of the research is to harness areas such as AI/reasoning/machine learning alongside research in Human Computer Interaction to develop new approaches to supporting pilot decision making, thereby enabling pilots to diagnose and respond more safely and effectively to the complex abnormal or emergency situations that they will encounter when flying modern aircraft.

Project Outlier detection in data streams Institute for Integrated and Intelligent Systems Data streams are sequences of data that are continuously transmitted to a receiver. Outlier detection is to identify abnormal data, or data that are significantly different from normal data. The problem of detecting outliers from data streams has important applications and has attracted a lot of attention from researchers. However, there are still many challenges in accurately and efficiently identifying outliers, that is, how to effectively distinguish normal data from outliers, and how to achieve real-time identification. This PhD project aims to develop novel techniques for the problem. Data Management and Analysis ITScience	Associate Professor John Wang
Project Fast Approximation algorithms for subgraph queries Institute for Integrated and Intelligent Systems Graph data are ubiquitous nowadays. Real-world graphs (e.g., social network graphs, knowledge graphs, road networks) are getting larger and larger, which makes many common graph queries (e.g., subgraph matching/counting, crucial nodes/edges identification, cohesive subgraph computation, constrained shortest paths) time-consuming. However, in many real-world applications, approximate answers are sufficient and much easier to find. This PhD project aims at developing novel techniques for the fast finding of approximate answers, focusing on subgraph computation/counting queries.

Project Micro/nano-plastic detection and classification using dark-field hyperspectral microscopy Institute for Integrated and Intelligent Systems Micro- and nano-plastic debris in aquatic, terrestrial and marine habitats have become significant concern for human health. Due to their tiny size, developing a high-throughput system to detect and classify them is a challenging task. It has been proven that shortwave hyperspectral imaging technology is highly effective in classifying plastics in the size of tens of micrometers. Nevertheless, when the size of plastics reduces to sub-micrometer or nanometers, traditional hyperspectral microscopic system becomes infeasible. This project aims to develop an innovative technology for micro/nano-plastic detection and classification using dark-field hyperspectral microscopy.

Project Segmentation of powerline corridors in complex environments Institute for Integrated and Intelligent Systems Conductors in powerline corridors are thin, so only a small number of laser points get reflected, which makes it difficult to effectively extract the conductors using the aerial point cloud data. We have recent success in extraction of the conductors even when conductors are in bundles of 2 or 4 sub-conductors. However, power line corridors often exist in complex environments (e.g., forests), where occlusions, missing data and noise are regular phenomena. The advancement of recent deep learning techniques will be useful for high-performance powerline corridor segmentation in complex environments.

Project Deep learning-based building roof part segmentation Institute for Integrated and Intelligent Systems The 3D object reconstruction is highly challenging due to high data complexity, structural variations, presence of noise, and missing of data. Buildings come in different shapes and their unique architectural designs pose a great challenge, specifically for extraction and modelling of small components such as chimneys. The recent deep learning architectures have shown high success in object-part segmentation, e.g., a plane can be divided into wing, body, fin, and stabilizer. So, prior knowledge about a building roof style can be sought as a prerequisite step for building roof reconstruction.

Project Trusted Automatic Programmer via Generative AI and Formal Methods Institute for Integrated and Intelligent Systems Large language models (LLMs) are disruptive tools for software engineering and many other industries. In particular, people have used LLMs to develop automatic programmers.

Project Quantum Program Verification Institute for Integrated and Intelligent Systems Software testing can only show the presence of bugs but never their absence, so it is crucial to mathematically prove the correctness of programs in mission-critical domains such as aerospace, defence, finance, health, etc. This practice is called formal (program) verification. The advancements in quantum computing extend the application of formal verification to quantum programs, which is uncharted territory. This project will develop new verification techniques that are suitable for quantum programs, possibly using quantum computing algorithms. Quantum Computing ICT	Dr Zhe Hou

Project Accurate estimation of sugarcane yield from aerial remote sensing data Institute for Integrated and Intelligent Systems Crop yield estimation plays a significant role in management of agricultural activities and decision making, such as fertiliser (e.g., nitrogen) use, crop insurance, harvesting and storage requirements, and budgeting. Visual yield assessments by growers or agronomists could be highly subjective and labour intensive. Methods based on satellite RGB image along with existing agronomic and meteorological data compute in-season vegetation indices often estimate yield for an entire district or region, so they lack in farm-specific yield estimation. Moreover, sugarcane yield estimation does not depend much on the 2D spectral information (i.e., leaf-colour), rather on the plant height and stalk density. Thus, the project will investigate the use of 3D point (aerial laser scanning) data for accurate sugarcane yield estimation. These data will provide important cues to estimate number and density of sugarcane stalks. Artificial Intelligence EnvironmentalScience	Dr Mohammad Awrangjeb

Project Artificial Intelligence Support for Adaptive User Interfaces Institute for Integrated and Intelligent Systems In both real and simulated environments, people can be overwhelmed if exposed to high levels of competing stimulus which can negatively impact cognitive load. When using immersive technologies, for example for augmented reality, there are opportunities to add useful virtual objects into a real-world environment both as objects located in 3D space and as part of an extended user interface (UI), i.e., a head-up display (HUD). These elements need to be managed as not to diminish user experiences. This project will explore intelligent agents (AI support) to enable user-initiated UI adaptation and pre-empt the need for UI changes based on user, task and environment contexts, for example monitoring physiological sensors for indications of user distress (cybersickness, heart-rate increase) and/or contextual cues in real/virtual environments that may indicate that there is a need to reduce any augmented stimulus and/or dynamically reconfigure the user’s current user interface.

Project Automation of Cyber Threat Intelligence phases using Machine Learning Institute for Integrated and Intelligent Systems Cyber threat intelligence (CTI) refers to knowledge about potential threats, which includes information on threat indicators such as Tactics, Techniques, and Procedures (TTPs), IPs, and more. CTI can help organisations identify existing threats, either through external open-source threat intelligence or by monitoring adversarial activities within their own networks. The generated CTI can be used to build intelligence about threats against a specific target. Initially, indicators of compromise (IoCs) are generated, and these IoCs can be processed and shared using CTI sharing techniques. Such techniques allow security analysts to use CTI information from other companies and share their IoCs with trusted partners, which can be used to update detection rules and blacklists in security devices such as IDSs and firewalls. To enable effective and collaborative cyber threat intelligence sharing, the application of state-of-the-art machine learning techniques in the CTI generation and sharing should be investigated. This project will review automation of CTI generation and sharing using machine learning . The efficacy of using machine learning technology for detecting network attacks has been widely studied, but it has been difficult to create an ML-based detection system that can handle diverse network data samples from different organisations. This project aims to propose an automated cyber threat intelligence sharing using machine learning that enables multiple organisations to work together to share their IoCs.

Project Enhancing Cyber Security of Cyber Physical Systems through Digital Twins Institute for Integrated and Intelligent Systems The progress made in fields such as the internet of things, artificial intelligence, machine learning, and data analytics has facilitated the development of digital twin technology. A digital twin is a high-fidelity digital model of a physical asset or system that can be utilised to optimise operations and predict faults of the physical system. Operators of cyber-physical systems need to be aware of the cyber situation in order to adequately address any cyber attacks in a timely manner. Early detection of cyber threats can quicken the incident response process and mitigate the consequences of attacks. However, gaining a complete understanding of the cyber situation may be difficult due to the complexity of cyber-physical systems and the ever-changing threat landscape. More specifically, cyber-physical systems (CPSs) usually have to be continuously operational, and they may be sensitive to active scanning of the network traffic. Digital twins can address these challenges by providing virtual replicas of physical systems that can be analysed in-depth without disrupting operational technology services. This project aims to assess the usefulness of digital twins for the cybersecurity of cyberphysical systems and review the tools and technologies available for creating them. Additionally, a cybersecurity framework for anomaly detection using digital twins in cyber-physical systems will be proposed. Cybersecurity Technology	Dr Zahra Jadidi
Project Explainable machine learning in intrusion detection systems Institute for Integrated and Intelligent Systems Over the past few years, many intrusion detection systems (IDSs) have been developed using machine learning methods. These automated IDSs can automatically analyse network data, including network traffic and device logs, to detect intrusions. Cybersecurity experts rely on these systems' recommendations to improve network security. To enhance the reliability of IDSs, it is important that the decisions made by these machine learning-based solutions can be justified to humans. However, the current automated IDSs are used as black boxes, providing no information about the reasons behind their predictions. It should be clear to cybersecurity experts which features of the network data caused the intrusion. This project aims to identify state-of-the-art techniques to develop an explainable IDS, addressing this gap and providing a better explanation of IDS decisions. It will investigate how existing methods can be improved to provide more comprehensive interpretability of machine-learning-based IDSs and provide details about the features involved in IDS decisions.

Project Adversarial Machine Learning in Cybersecurity Domain Institute for Integrated and Intelligent Systems Modern Intrusion Detection Systems (IDSs) play a vital role in safeguarding information technology (IT) networks against cyber-attacks. IDSs rely on machine learning techniques to analyse network traffic and identify suspicious patterns and anomalies that may indicate an ongoing or impending attack. However, the deployment of these machine learning-based systems has introduced an additional vulnerability, as the models they use to detect and respond to threats may also be subject to attacks. This type of attack is known as Adversarial Machine Learning (AML) and involves exploiting the underlying machine learning algorithms to evade detection, misclassify data, or manipulate the training process. This project will study AML techniques in cybersecurity domain and propose defence strategies. Cybersecurity Technology	Dr Zahra Jadidi
Project Cybersecurity in Industry 5.0 Institute for Integrated and Intelligent Systems As the use of connected devices and the Internet of Things (IoT) becomes more prevalent in manufacturing processes in the Fifth Industrial Revolution (Industry 5.0), cybersecurity becomes a critical consideration.

A significant cybersecurity challenge in Industry 5.0 is protecting the data generated by connected devices. This information is often confidential and valuable, and unauthorised access to it can disrupt operations or result in intellectual property theft. To counter this risk, it is crucial to encrypt, securely transfer and store data to prevent unauthorised access. The project will study the new threat landscape in industry 5.0, and propose mitigation strategies for the new vulnerabilities introduced by the Fifth Industrial Revolution.

The algorithms will be applied to disaster management and recovery. Artificial intelligence, Optimisation, Computational Intelligence ICT	Dr Mardé Helbig
Project Improving the accuracy of GenerativeAI with fine-tuning of base LLM with domain specific data Institute for Integrated and Intelligent Systems While supervised learning is known for a while introduction of pretrained transformers reduced the demand and therefore the cost for annotation of training data. Pretrained transformers learn from large amounts of unlabeled text data and are a form of Large Language Models (LLM). Another milestone in AI was the introduction of the Generative Pretrained Transformers (GPT) framework, which has a decoder layer and is able to understand and generate human-like text. The popularity of OpenAI ChatGPT revolutionised the GenerativeAI. While these models provide huge benefits training such models is time-consuming and costly, which causes the information in such models to be not up to date. For example, popular ChatGPT3.5 was trained with data generated prior to January 2022. There are approaches to finetune smaller base LLM with domain-specific data, however, further improvements are needed to improve accuracy, reduce hallucination and ensure information generated from such models is up-to-date.

Project Forgetting while fine-tuning Large Language Models Institute for Integrated and Intelligent Systems The popularity of OpenAI ChatGPT revolutionised the GenerativeAI. While these models provide huge benefits training such models is time-consuming and costly, which causes the information in such models to be not up to date.

One particularly insidious threat is the emergence of backdoor attacks, which involve stealthily implanting malicious features or patterns during model training, enabling unauthorised access or manipulation of the neural network's behaviour under specific conditions, compromising its integrity and functionality. Notably, recent reports have raised suspicions about a significant number of pre-trained DNN models from Model Zoo being vulnerable to backdoor attacks. This project investigates backdoor attacks on DNNs, aiming to expose attack mechanisms, assess real-world implications, and propose detection/mitigation strategies for robust AI systems. The exploration includes defining and elucidating backdoor attacks, examining implantation techniques, showcasing instances, and consequences, and analysing recent cases for lessons.

Project Understanding and Resisting Adversarial Attacks in Deep Neural Networks Institute for Integrated and Intelligent Systems In the era of rapidly advancing artificial intelligence, deep neural networks (DNNs) have become indispensable tools for various applications. However, as the reliance on these models grows, so does the concern over their security. One particularly insidious threat is the emergence of adversarial attacks, wherein malicious actors deliberately manipulate input data to deceive deployed DNNs, leading to misclassifications or compromised performance. These attacks pose a significant challenge, demanding a comprehensive understanding of their mechanisms and the development of robust defences. This proposal aims to delve into the intricacies of adversarial attacks, exploring their impact on DNNs and proposing effective strategies to fortify these models against such sophisticated threats.

Project Privacy Attacks and Defences in Deep Neural Networks Institute for Integrated and Intelligent Systems In the era of rapidly advancing artificial intelligence, deep neural networks (DNNs) have become indispensable tools for various applications. However, as the reliance on these models grows, so does the concern over their privacy leakage. Notably, instances such as ChatGPT inadvertently revealing its training data through deliberately designed prompts underscore the pressing need to address privacy vulnerabilities in DNNs. This proposal seeks to delve into the vulnerabilities of DNNs to privacy attacks, examining potential threats stemming from learning paradigms, model architectures, training data, training processes and inference outputs. By understanding these risks, the project aims to develop robust privacy-preserving mechanisms and effective defences against privacy leakage, ensuring that the deployment of DNNs aligns with stringent privacy standards.

Project Development of new drugs to treat parasite infection and overcome drug resistance Griffith Institute for Drug Discovery Parasites including Plasmodium (causes malaria) and Toxoplasma gondii (causes congenital birth defects) lack effective vaccines and drug treatments remain the only therapy, yet few exist, and drug-resistance limits their use. PROTACs are an emerging technology, which show great promise in limiting drug resistance in a range of human conditions and are in clinical trials, yet there is a lack of research into PROTAC-mediated targeting in parasites. In this proposal we will address this shortcoming and provide a pathway to augment and limit resistance of current and emerging drug therapies, for these parasites with PROTACs.

Project Development of a chemical synthesis strategy for the manufacture of mRNA with improved properties Griffith Institute for Drug Discovery Currently mRNA manufacture is expensive, slow, can result in impurities and a product with low stability. In principle, the chemical synthesis of mRNA could overcome these limitations. However, current solid phase RNA synthesis methodology is restricted by the length of RNA it can produce. This project aims to develop a strategy for the solid phase chemical synthesis of mRNA, overcoming all limitations of current synthesis to transform the way mRNAs are made. This is expected to deliver significant improvements in RNA sequence length, quality, incorporated modified bases and capping groups than is presently possible. The new synthesis will be applied to produce stable peptide-encoding mRNAs. Chemistry, Chemical Biology ChemicalSciences	Professor Sally-Ann Poulsen
Project Insight into Diffusion models Institute for Integrated and Intelligent Systems Diffusion models, a recent addition to deep generative models, have shown exceptional performance across diverse applications such as image generation, audio synthesis, and scientific research. Despite their promising results, challenges hinder their broader adoption in scientific research and applications. These challenges encompass computational demands, interpretability issues, data prerequisites, uncertainty quantification, and concerns regarding biases and precise control over the generation process. This project is dedicated to overcoming these barriers to unlock the full potential of diffusion models in scientific research and applications.

AI, Computer Vision, Machine Learning, Deep Learning ICT	Professor Yongsheng Gao
Project Insight into ViT models Institute for Integrated and Intelligent Systems Vision Transformers (ViTs) represent a recent breakthrough in computer vision, adapting the Transformer architecture from natural language processing (NLP) to image recognition tasks. ViTs have garnered attention for their capability to capture long-range dependencies in images without using convolutional operations. However, achieving robustness and generalisation with ViTs poses challenges. Additionally, developing efficient transformer models tailored for computer vision remains an open problem. This project aims to explore novel transformer architectures, algorithms, and techniques to address these limitations.
