3D Data Visualisation and the Metaverse

Virtual environments in the Metaverse provide almost infinite visual real estate for interacting with 3D data visualisations. This provides opportunities for novel deployment of large data sets across diverse domains, including health, climate, education, defence, cybersecurity, blockchain, etc. However, there are significant challenges to useful data engagement in the Metaverse where information and users may be distributed across environments but still need to collaborate. This project will explore the visualisation of 3D data using immersive head-mounted displays that support eXtended Reality (XR) and develop new paradigms for virtual and real-world data interaction into, within and out of the Metaverse.

A new therapeutic model for Parkinson's disease: physiological and pathological roles of potassium channels

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.

Accurate estimation of sugarcane yield from aerial remote sensing data

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.

Adaptation of the whale watch industry to climate change

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.

Adaptive Privacy Protection for Medical Data

With the evolution of modern information technology, medical data sharing has become a part of our daily life, which greatly benefits medical research and development professionals, service providers and the society as a whole. The rapidly growing volume and variety of medical data in the past decade has made privacy protection an increasing concern to data owners, obstructing medical data sharing to reach its expected scientific and market value. This project will focus on a solution to provide an adaptive protection for medical data so that data users can create the explainable intelligence based on the shared data without disclosing any privacy information.

Advance native MS methods to membrane proteins enable screening of small molecules against this important class of targets

These tailored 2D nanomaterials will significantly improve the performances of flexible and energy-related devices.

Adversarial Attacks on Machine Learning-Based Models in Cybersecurity of Cyber-physical 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.

Adversarial Machine Learning in Cybersecurity Domain

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.

Air route development - feasibility calculation

Air route development (ARD) is a well-known business process within airports and airlines. Airports are usually perceived as leading partners in this stakeholder engagement, aiming to attract new and retain existing airline partners. Still, multiple other stakeholders are involved in the process, and their support or lack of it significantly impacts the sustainability of a particular route. This project aims to propose new ARD feasibility calculation methods that airports, airlines, and other involved stakeholders could use as decision-making tools. Commercial air routes are the primary focus of this project, with the potential to extend it to cargo routes.

Ameliorating microglia-mediated neuroinflammation for Parkinson's disease therapy

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.

Ancient DNA

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.

Antibiotic-nanoparticle conjugate systems and their effectiveness assessments against gram negative bacteria

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.

Antimicrobial probiotics and mechanism study

The inclusion of probiotics in animal feeds have proven to be beneficial to animal health. This project is a collaborative research program between Griffith University and Bioproton, aiming at investigating the mechanism of action of probiotics that have antimicrobial activity. The outcome of the project will lead to scientific discovery on the antimicrobial behaviours of probiotics. The active Bacillus strains can be used as effective antimicrobial agent in animal feed materials.

Application of biocatalytic protein cages in drug discovery and metabolism.

We have developed a number of virus-derived protein cages into robust containers for enzymes.

There are a number of project opportunities on the application of biocatalytic protein cages in drug discovery and metabolism.

Artificial Intelligence facilitates ICU Resource Management against Infectious Diseases

Respiratory infections and antibiotic resistant bacterial infection are some of the conditions that have significantly stressed our hospital ICU. A number of risk factors have been reported to associate with severe diseases, which includes age, pre-existing conditions, pathogen setpoints, responsiveness to therapeutic strategy. Any single risk factor is unlikely to be an absolute determinate of clinical diseases, rather many contributors or associations are important with the disease progress. We will use ICU data and artificial intelligence to generate a prediction algorithm to assist clinical decision making.

Artificial Intelligence Support for Adaptive User Interfaces

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.

Assessing the impacts of chemical pollutants on marine wildlife using novel and ethical techniques

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

Atomically Thin 3d Transition Metal Electrocatalysts for Water Splitting

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.

Augmented stream learning of medical time series data for continuous outcome prognosis

This project aims to develop novel stream learning algorithms for continuous patient outcome prognosis by taking into account patient's data collected during ICU admission in a unified manner. The algorithms are expected to integrate high frequency time series data with patient's demographic data, lab data, diagnosis data, prescription data, etc. as exemplified in MIMIC-III, for accurate outcome prognosis. Issues such as prediction bias, data leakage, data sparsity, non-stationarity, model explainability will be investigated.

Automated cyber threat hunting using NLP

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).

Automated monitoring of restored marine environments

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.

Automation of Cyber Threat Intelligence phases using Machine Learning

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.

Better prediction of chemistry on computers (applied mathematics/physics project)

Suits students with a strong interest in applied mathematics and computers. Machine learning techniques will likely feature in this project.

Biosolid-based biochars for agricultural carbon sequestration

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.

Biotechnology with persistent plant viruses

We have determined the first structure of a persistent plant virus. It is not clear what advantage these asymptomatic viruses confer in order to maintain the purported symbiotic relationship they have with their hosts. Understanding the form and function of persistent viruses through molecular and structural biology will open many possibilities for their use in plant biotechnology.

Blue-green algae and their toxins - can we manage them in a changing climate?

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.

C. elegans as a model system to characterise the role of a metabolic master regulator

Previously we showed the enzyme dihydrolipoamide dehydrogenase (DLD) to be a metabolic master regulator. We now will characterise the role of DLD in the metabolic network of C. elegans by using metabolomics and biophysical techniques in isolated mitochondria, as well as curating the genome scale metabolic model of C. elegans in collaboration with the WormJam consortium and simulating the nematode’s metabolism.

Can restoration recover lost ecosystem services?

As restoration projects gain traction during this Decade for Ecosystem Restoration, we need to develop techniques that secure the success of these projects and achieve expected outcomes. The project works with many stakeholders including Traditional Owners, farmers, State Government and local council to determine whether ecosystem services, including nutrient retention, carbon sequestration and biodiversity, develop within current wetland restoration projects.

Can we use revegetation to control algal blooms? The role of organic matter leached from trees

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.

Cascading failure attacks against smart grids

Electric power systems are considered critical infrastructure and are susceptible to various contingencies such as natural disasters, system errors, and malicious attacks. These contingencies can have a severe impact on the world's economy and cause significant inconvenience to our daily lives. Hence, the security of power systems has been a topic of considerable interest for decades. With the recent development of the Internet of Things (IoT), power systems can support various network functions throughout the generation, transmission, distribution, and consumption of energy through IoT devices like sensors and smart meters. However, this has also led to an increase in security threats. Cascading failures are one of the most severe problems in power systems and can result in catastrophic impacts such as widespread blackouts. Furthermore, these failures can be exploited by malicious attackers to launch physical or cyber attacks on the power system. This project aims to investigate cascading failure attacks and develop AI techniques to detect and defend against them. Feel free to contact me for further discussion.

Cell transplantation and drug options for peripheral nerve repair

Peripheral nerve injuries are devastating as they can result in permanent paralysis.

Chlorine Evolution Catalysts for Efferent Seawater Electrolysis

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.

Combating Giardiasis by investigating new potent compound series as leads for improved treatments

Giardia parasites infect approximately 1 billion people and cause over 200 million cases of giardiasis each year. They also cause significant morbidity in animals. However, current treatments are inadequate, associated with resistance and collateral microbiota impacts. This project aims to improve the treatment of giardiasis by investigating the biological and pre-clinical activity of potent new anti-Giardia compounds in animal models of infection.

Computational Science and Engineering

Computational science and engineering is a modern approach to research, distinct from standard theoretical and experimental approaches. In computational research, fast computers are used to simulate or model the behaviour of physical systems to better understanding properties too difficult or expensive to study via experiments. Nano- and micro-scaled systems can pose a particular challenge for conventional experiments and theory, and are a natural fit for computational study.

Construction of a bioengineered choroid to study regenerative healing

Macular degeneration causes devastating visual impairment in the Australian population, and without new and effective treatment options, one in seven Australians with early signs of macular degeneration will likely progress towards advanced stages of the disease. The earliest known pathophysiological event to occur in macular degeneration is choroidal vascular dropout, and little is known about the events that occur prior to this microvasculature dysfunction and the contribution of the surrounding choroidal stroma and its resident cell populations. This project aims to construct a multicellular bioengineered choroid to elucidate deeper understanding about this specialized sensory support tissue.

Continuous beam atom interferometers for quantum enhanced navigation

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.

Coordination in multiagent swarms

Coordinated action by multiple agents (such in robotic swarms), is an important area, especially whe there is limited or only intermittent communication. This requires both local planning and adjustment when there is a possibility to coordinate, so that the swarm as an emergent agent can fulfill an overall intent. The work would involve literature review, theory building, and validation through simulation experiments (using a multi-agent simulation platform).

Counterfactual quantum smoothing

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.

Cumulative effects of light and chemical pollution on circadian systems in fish

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.

Cybersecurity in Industry 5.0

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. The integration of these devices presents new opportunities for cybercriminals to exploit vulnerabilities and attack the system, hence organisations must implement robust cybersecurity measures to safeguard their data and systems. 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.

Deep learning-based building roof part segmentation

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. The project aims to employ deep learning architecture to segment a roof into parts and then classify them into roof styles before the roof is reconstructed as a complex shape.

This project aims at providing fundamental knowledge of the ecological processes involved in macroalgal blooms in the GBR.

EEG Biometrics

Electroencephalography, or EEG for short, is a technique that measures the electrical activity of the brain through electrodes placed on the scalp. This non-invasive and cost-effective technique has been used in various fields, including neuroscience research and clinical practice. One of the main reasons why EEG research is so important is because it allows us to gain valuable insight into brain function and dysfunction. It has been extensively used to investigate a wide range of cognitive processes, such as attention, perception, memory, language, and emotion. Furthermore, EEG has been instrumental in diagnosing and monitoring neurological disorders, including epilepsy, sleep disorders, and traumatic brain injury. Overall, EEG research is an essential tool for understanding the human brain and its disorders. This project focuses on research on EEG biometrics and its applications.

Enacting 'procedures as resources for action' approach through new technology and IT system

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.

This project expects to have various benefits for Australians – through the development of a cutting-edge sustainable energy device and the establishment of strong international collaborations.

Enhancing Cyber Security of Cyber Physical Systems through Digital Twins

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.

Entropy-tuned alloys for hydrogen storage

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).

Environmental impact of firefighting chemicals and bushfire leachates on aquatic ecosystems

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.

Gullies are the majority source of sediment discharged into the Great Barrier Reef, motivating significant investment to prevent erosion and improve water quality in receiving environments. Large amphitheatre gullies are complex structures with highly variable erosion processes. Process-based models are required to inform rehabilitation practices, and to inform investment at the catchment scale. This project will develop models of gully erosion suitable for informing management in ampitheatre gullies. This project will involve collaboration with Queensland Government and the Queensland Water Modelling Network and is associated with an ARC Industry Fellowship.

Explainable machine learning in intrusion detection 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.

Exploring new biological targets for treating Parkinson’s disease – from patients back to patients

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.

Exploring the immuno-modulatory effect of fungal beta-glucans

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.

False alarm detection and removal through contextual reasoning for Cyber Security

In today’s digital ecosystem world, we see more and more intelligent devices are connected over the Internet, enabling them to share their data on the Web. This allowed us to collect a large amount of data and use then for intelligent situation awareness and intrusion detection. This research will address the key issues facing to cyber security: 1) big streaming data analysis, 2) the huge number of generated alarms with the vast majority being false alarms, 3) human effort to investigate alarms to find intrusions, 4) determination and removal of false alarms, 5) timely decision making in a constantly changing environment, and 6) the ability to capture previously unknown attacks.

Fast Approximation algorithms for subgraph queries

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.

Key themes include: safer, greener forensic processes; delivering new functionality or clearer interpretation; and interdisciplinary, practitioner-informed research.

Forgetting while fine-tuning Large Language Models

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. Proposed methods to finetune smaller base LLM with up-to-date data do not necessarily discard irrelevant outdated data from Large Language Models. This work will look into options to ensure finetuning of the models forgets only desired parts and does not cause catastrophic forgetting due to multiple model fine-tuning.

Formal modelling of the semantics of programming languages

This project investigates the semantics of popular programming languages at different levels. For instance, we will formally model the semantics of a high-level programming language, such as rust, in a formal verification tool, such as a theorem prover, to understand exactly how a piece of code works and whether it is correct with respect to the user specifications. We will also model program semantics at a lower level (e.g., compiled binary code) and check whether low-level semantics conforms with high-level code. The formal modelling of the programming language of choice should lead to verification tools with practical impact in the industry.

Formulation and application of deep learning and other AI techniques to physical sciences

The current wave of deep learning and AI research has yielded many advances in how tools such as neural networks, optimization, or uncertainty quantification can be used to improve modelling capability for a number of useful applications. Projects are available in the development of robust and transparent machine learning and AI techniques that can be employed to augment existing computational modelling techniques (e.g. surrogate models, reduced order models, etc) or to provide new avenues of solution (e.g. PINNs as a famous example).

From trapping a single cell to unravelling DNA

Life is the dynamics of large biomolecules. This project aims to develop a novel experimental approach to achieve atomic levels of control over large biomolecules through manipulation of electrostatically levitated bioparticles in a Paul trap. This starts with single yeast cells and will progress to developing laser and electron optics techniques to controllably fragment the cell into organelles and into isolating single chromosomes. These chromosomes will then be controllably and potentially reversibly unfolded using single electron changes in the static electrical charge to demonstrate an atomically resolve force microscopy.

Fundamental thermodynamics of metal - hydrogen systems

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.

Fusion of symbolic and sub-symbolic computation (towards AI that displays general intelligence)

Current AI/ML techniques are limited in terms lacking meta-cognition that allows a system to reason about its own abilities and capabilities in light of the problem space encountered. The project would suit a candidate who is interested in both the theory of AI and in experimenting with implementation tools to build efficient and effective AI systems (e.g. SOAR, CLARION, ACT-R,...).

Gender equality in Aviation - From academia to industry boards

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.

Gene networks associated with neurological disorders: the key to better diagnostics and treatments

Neurological disorders such as schizophrenia and dementia are caused by a ‘perfect storm’ of unique combinations of genetic and environmental factors. Such complex combination of events leads to disruptions in gene networks and biological pathways that alter cell functions and consequently influence disease risk. New approaches in genomic technologies, computational models and experimental systems could potentially lead to personalised treatment based on an individual’s genetic composition. This project aims to map molecular networks and cell functions affected in patient-derived stem cells to help discover new therapeutic strategies tailored based on patient’s molecular and cellular signatures.

Generating and sharing cyber threat intelligence in industrial control 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. It will also investigate how threat intelligence can be automatically created and shared for new emerging attack and link the CTI to cyber security defence mechanisms.

Generating high-quality reference genome assemblies for Australian Papaya varieties

We are currently looking for a PhD candidate to develop genomic resources and tools for Australian papayas to facilitate future smart breeding of elite varieties. The primary objectives of this role are to: (a) sequence and annotate the reference genomes of selected Australian papaya varieties and (b) develop high-density genetic markers for Australian papaya and wider germplasm collections. The goal is to then uncover genomic sequences that may be used for accurate selection of preferred flavour and productivity traits across a broad germplasm set. Outputs from this project will directly contribute to genomic prediction approaches for developing elite papaya varieties. This project includes molecular, genomic and transcriptomic approaches that will leverage prior knowledge and skills developed in our group and by collaborators. These include high density SNP mapping and QTLs underpinning several fruit quality traits and possible gene candidates, as well as trained sensory panel and biochemical profiling performed to identify volatiles and other compounds that are associated with distinct fruit flavours. Success in this role requires collaboration with fellow team members and leading researchers from the University of Queensland, Murdoch University and the Queensland Department of Agriculture and Fisheries.

Genetic toolkits to preserve biodiversity and functions in coastal and marine ecosystems

Australia's expansive coastal and marine ecosystems are in dire need of improved biological monitoring to preserve their valuable and unique biodiversity in the face of human-related disturbances. This Project responds to the challenge by upscaling and revolutionising fit-for-purpose genetic toolkits that can extract whole ecosystem DNA data from environmental samples. This innovation will be done in the interest of answering previously inaccessible ecological questions related to biodiversity, supporting habitat restoration and engineering solutions, complementing rather than replacing existing biological monitoring, supporting commercial outcomes with automation, and benchmarking the health of coastal and marine ecosystems under threat.

Geochemistry of critical metals in coastal and marine waters

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.

Graph Neural Networks for Drug Discovery

Graph neural networks (GNNs) are emerging techniques for AI. As many chemical compounds and proteins in biology can be modelled as graphs, GNNs have great potentials for drug discovery. This research will investigate new GNN based techniques to accelerate the process of drug discovery.

Graphical program analysis

Through previous work with Prof Bernhard Moller and Turing Award Laureate Sir Tony Hoare, we proposed a geometric theory for program analysis in which a computer program is represented by dots and lines in a diagram. Prof Moller has laid out the theoretical foundation of the work, and we are now ready to proceed into a more practical development. Our vision is to build a program analysis tool with Graphical User Interface (GUI) that supports writing and modelling programs by drawing diagrams and automatically translating a diagram into an executable program. A diagram can also be converted to a Communicating Sequential Process (CSP) model in our tool Process Analysis Toolkit (PAT) and be used for model checking. The outcome is a toolchain that supports user-friendly program analysis, testing and verification.

Greenhouse gas emissions from wetland disturbance

Wetlands can accumulate large amounts of carbon, but when disturbed, this carbon can be released into the atmosphere as CO2 and CH4, contributing to global warming. This project aims to determine how disturbances, including hydrological modifications, feral animals and deforestation, affect the carbon cycle of wetlands (mangroves, marshes and supratidal forests) and how can these be reversed.

Harnessing the power of the macrophage: innovative anti-cancer drugs known as 'maca-attackers'

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.

High-temperature superconductivity in palladium deuteride

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.

High-throughput Double Emulsion Using Microfluidics

Double emulsions, referring to droplets of the disperse phase containing even smaller ones, are highly desirable for applications in drug delivery, food science, release of substances, etc., due to the embedded structure which can encapsulate different types of molecules. This project aims to produce and control high-throughput double emulsions using microfluidics.

Hunting for new bioactive natural products from Australian rainforest and desert plants

Humans have utilised plants since the dawn of time for therapeutic purposes. Many important and well-known drugs (e.g. taxol, morphine) come from plants. Endemic Australian rainforest and desert plants have yielded many new and bioactive natural products, but remain under-investigated. This project will result in the purification and characterisation of new bioactive compounds, and that will impact biodiscovery.

Hyperspectral video processing

Hyperspectral videos contain rich spectral, spatial and temporal information of moving objects. The goal of this project is to develop fundamental hyperspectral image analysis, object detection and tracking methods and explore their applications in agricultural, environmenal, and medical applications.

Identification of a vessel wall directed therapy to treat heart disease

The cells of blood vessels produce sticky molecules called proteoglycans and once modified can bind and retain cholesterol. Zebrafish express all the major receptors, lipoproteins and enzymes involved in atherosclerosis and a complete set of genes to proteoglycan synthesis and modification. This project will develop a high-fat diet-induced zebrafish model of atherosclerosis to allow for screening of potential vessel wall directed therapies to prevent cholesterol binding.

Identifying biomarkers for Parkinson’s disease as a step toward a cure

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.

Identifying new compounds active against Trichomonas Vaginalis

Trichomoniasis is a neglected parasitic disease that causes significant morbidity in pregnant and elderly women (over 100 million infections each year). However, the only FDA approved therapy for this disease is associated with treatment failures and adverse effects. This project aims to develop and implement a new medium to high-throughput assay to identify and investigate new drug leads for trichomoniasis.

Impacts of bushfires on water quality and biogeological processes in Eastern Australia

The project will assess the impacts of bushfires on water quality and biogeochemical processes within Eastern Australian waterways to better understand the short- and long-term impacts of bushfires on aquatic biogeochemical cycles in estuaries. The fate, transport, and cycling of target metals and nutrients (Fe, Mn, C, N, P, S) will be the focus of this study with both laboratory and field-based experiments utilised. 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 be based at either location. Focus areas are bushfire-related aquatic biogeochemistry, environmental pollution, and environmental chemistry.

Impacts of disease and environmental contaminants on wildlife conservation

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.

Improving the accuracy of GenerativeAI with fine-tuning of base LLM with domain specific data

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.

Incorporating decision-maker preferences for dynamic multi-objective optimisation

Many real-world problems have multiple, conflicting objectives and/or constraints that are dynamic in nature. These problems are reffered to as dynamic multi-objective optimisation problems. Nature-inspired population-based algorithms enable natural parallel search for a set of optimal trade-off solutions. This study will investigate how a decision maker's preferences can be incorporated in the dynamic search, to focus the search around more preferred regions of the optimal trade-off solution set in an interactive and dynamic way. The algorithms will be applied to disaster management and recovery.

Interaction of attosecond light pulses with atoms and molecules

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.

Blockchain has been showcased as a game changing national technological strategy in several countries. This project will extend our current work on the classification of digital assets, cross-chain integration protocols, and formal verification of smart contracts with novel design patterns and formal security guarantees for inter-blockchain systems. Experiments and validation will be carried out on test-networks and using real-world case studies with our industry collaborators

Interpretable learning in biomedical image analysis

Due to the “black box” characteristics of the deep learning technique, the deep network-based computer-aided diagnosis systems have encountered many difficulties in practical application in healthcare. The crux of the problem is that these models should be explainable – the model should give doctors rationales that can explain the diagnosis.The objective of this project is to research on highly interpretable algorithms to generate "trust" between the human users and the algorithm, designing user-friendly explanations and developing comprehensive evaluation metrics to further advance the research of interpretable machine learning in biomedical image analysis.

Investigation of cyclization - blocked proguanil analogues for malaria

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.

Is New Guinea the missing link for understanding Australia's rainforests

We are offering two Ph.D scholarships for motivated students to work on patterns of species richness and turnover across Australasia, with emphasis on drivers of biotic interchange between Northern Australia and New Guinea. Depending on background and interests, students will have research, travel/fieldwork funds to support work on projects such as (a) diversity and systematics of key groups of frogs or lizards, or (b) broadscale projects on patterns and processes of biotic turnover, quantification of biodiversity hotspots, and implications for conservation.

Is nutrient offsetting a win-win for restoring our rivers and coasts?

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.

Knowledge Empowered Decision Making in Medical Data Processing

This project focuses on developing explainable AI solutions to decision support systems, by combining knowledge graphs, machine reasoning and machine learning. Knowledge graphs is a promising data and knowledge organisation, synthesis and management approach, and we have developed scalable reasoning tools for knowledge graphs coupled with ontological rules that describe domain knowledge or business rules. This project aims to study the problem of incorporating such high-level knowledge and formal reasoning in the analysis of cross-media data. Moreover, such knowledge and reasoning can be integrated with machine learning models to provide powerful support for informed decision-making where a justification or explanation of the decision can potentially be retrieved.

Knowledge Graph Reasoning at Scale

Knowledge graphs are important tools to enable next generation AI through providing explanation for different applications such as question answering. Knowledge graphs are typically sparse, noisy, and incomplete. Knowledge graph reasoning aims to solving this problem by reasoning missing facts from the large scale knowledge base. This project aims to develop novel scalable technique for knowledge graph reasoning. The developed techniques will be further generalised to more general graphs with graph neural networks.

Koala face recognition

AI-based human face recognition is a mature technology and has been adopted in many applications, such as mobile phone. However, recognition of animal face is still an under-investigated topic. Leveraging the success in human face recognition technology, this project aims to develop novel koala face recognition methods based on transfer learning using images and videos captured in the natural environment. The research outcome will leave to innovative tools for koala population estimation and conservation.

Land-based impacts on marine restoration efforts

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.

Land-based run-off in international conservation agreements

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.

Liquid biopsy-based biomarkers for oropharyngeal cancer

Oropharyngeal cancer (OPC) caused by human papillomavirus (HPV) is rapidly increasing globally, with an estimated 173,495 new cases in 2018. Approximately ~10-25% of patients develop recurrences within 2-years. The aim of this NHMRC funded project is to develop a microfluidic chip to permit capture of high-purity and viable circulating tumour cells (CTCs) to early detect recurrences in HPV driven OPC.

Mass spectrometry-based platform to develop novel Proteolysis Targeting Chimeras (PROTACs)

A novel approach called PROteolysis TArgeting Chimera (PROTAC) involves the development of bifunctional hybrid molecules that enable the target protein to be ubiquitinated to promote proteasomal degradation. We aim to develop the first native mass spectrometry-based platform that offers direct characterisation of ternary complex formation, population, stability, binding affinities, cooperativity, or kinetics by PROTACs and overexpressed proteins (both target proteins and ligases) in cells, overcoming the need for purification.

Mechanistic insights into heart disease and inflammatory bowel disease

Well defined risk factors such as high cholesterol, smoking, and high blood pressure worsen the burden of atherosclerosis. Patients with inflammatory bowel disease (IBD) present with a lower prevalence of classic risk factors, however, have at least a 2-fold higher risk of heart disease. Elevated inflammatory cytokines and an altered microbiome are observed in patients with IBD. This project seeks to define the biological link between IBD and heart disease by assessing the role of inflammatory cytokines and bacteria-derived toxins on vascular cells.

Micro/nano-plastic detection and classification using dark-field hyperspectral microscopy

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. The scope of the project includes hyperspectral image capture with dark-field microscopy, image processing, and machine learning method development for particle detection and classification. The student will work with a multidisciplinary team in ICT, Environment, Material Science, and Mechanics.

Modelling and optimisation of hydrogen-based energy systems

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.

Modelling bioparticle dynamics in an ion trap.

Trapped ions are a powerful tool for the analysis of charged bioparticles and biomolecules. Paul traps are used for high-resolution, long-duration confinement in this application. However Paul traps have selective stability depending on trap parameters and particle properties. This project would model the impact of permanent and induced electrical dipole moments on the theoretical stability of ion trajectories in a Paul trap and related the limits of electrical confinement of a charge point particle to an electric dipole in an optical tweezers.

Modelling neurodegeneration in the zebrafish and drug discovery

This project aims at establishing new zebrafish models of motoneuron degeneration or neurodegeneration per se. We will use state-of-the-art genome editing tools (optimised CRISPR/Cas9 approach) to manipulate selected genes of interest to both validate their predicted pathogenicity and generate animals developing neurodegeneration. These models will further be used to investigate the underlying degenerative mechanisms and establish drug screening/discovery programs.

Molecular targets program: rapid response to pandemics

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. As viruses contain very few proteins, this platform allows rapid response to viral pandemics. e.g. the discovery of anti-COVID19 anti-virals.

Multiphysics and flexible microfluidic technology

Microfluidics is both the science that studies the behaviour of fluids through microchannels and the technology of manufacturing microminiaturized devices containing chambers and tunnels where fluids flow or are confined. The previous works use rigid materials to construct the devices, and the device's functionality is mainly based on single physics. This project will design and develop a cutting-edge microfluidic technology by exploiting multiple physical coupling and flexible materials to achieve a variety of functions such as micropumps, micromixers, cell sorters, trappers etc. This technology will be applied in the lab-on-a-chip system for disease diagnosis, prognosis and treatment.

The project aims to develop technologies to generate nanobubbles and apply the gained nanobubble technologies in agriculture to treat biomass, in poultry and dairy to achieve fast promotion of animal growth, in aquaculture to increase productivity and feed-conversion ratio with short harvesting cycle, in catalyst chemistry for renewable energy, and in therapeutics to treat diseases

Nanomachineries for Exosomes and Exosomal Biomarkers Analysis

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.

Nanoparticle impregnated carbon as a reductive catalysis for environmental toxin removal

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.

Natural products drug discovery: New method to identify disease-associated drug targets

Target identification is crucial for rational drug design and is a current bottleneck for advancing bioactive compounds through the discovery pipeline. This project will use the power of native mass spectrometry to establish and validate a disruptive new platform to elucidate targets of bioactive compounds by direct detection of protein-small molecule binding. The proposed approach will accelerate current target identification as it will not need to modify bioactive compounds or proteins to achieve this outcome.

Neural Automated Reasoning

Complex formal proofs require significant effort and tools such as interactive theorem provers, whereas automated reasoners are often limited by the size of the problem or computational time. Recent advancements in machine learning have led to new tools, such as Sledgehammer, that use traditional theorem provers in smart ways to improve run time and automation. New algorithms such as HyperTree Proof Search applies ideas from Monte-Carlo Tree Search and deep reinforcement learning to push the boundaries of state-of-the-art theorem proving. This project aims to adopt the above ideas to develop new ML-based tools for Isabelle/HOL that can reason about logical formulae faster and more automatically.

New intelligent and human-centred approaches to supporting airline pilots’ decision making in complex situations to improve flight safety

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.

Next Generation Biometric Technology: Privacy-Preserving 3D Fingerprint Biometrics

The use of 2D fingerprint technology has become widespread in various authentication applications, such as mobile phones, laptops, and building access control. However, this technology has limitations, as it cannot fully replicate a real finger and is vulnerable to spoofing attacks. As a result, there has been a shift towards the development of 3D fingerprint biometrics, which offers benefits such as hygienic, contactless, anti-spoof, and natural representation. The aim of this project is to explore 3D fingerprint biometrics and to develop an AI-guided 3D fingerprint biometric system. The project will involve the application of AI/deep learning on 3D point cloud data. Feel free to contact me for further discussion.

Novel agents for anti-fungal drug development

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.

On-Farm' Devices and Technologies for Broad-Scale Disease Surveillance of Crop Plants

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.

Optimised Artificial Neural Network-based Cyber Intrusion Detection Systems

As the number of advanced cyber attacks is rapidly increasing in the modern world, it is crucial to detect attacks as soon as possible to prevent them from reaching their final goal and causing destructive damage. Therefore, a robust cybersecurity system is needed to detect and respond to potential cyber-attacks in a timely manner. Although automated intrusion detection using artificial intelligence has been proposed by many researchers, the performance of these methods still needs improvement. This project aims to review the applications of optimisation algorithms, such as the whale optimization algorithm (WOA), in improving the performance of networks (ANN)-based solution to detect cyber-attacks. Different optimisation algorithms will be analysed and compared to find the method that can outperform other methods.

Oral microbiome as a biomarker to early detect heart failure

Heart failure is a major global pandemic affecting more than 38 million people worldwide. It has been suggested that poor oral hygiene and periodontal diseases are related to a higher risk of developing cardiovascular disease. However, the underlying cause of this phenomenon has not yet been investigated. We are aiming to profile the oral microbiome content in patients with heart failure

Orchestration of Hybrid Agents and Autonomous Swarms

Traditional control techniques have limitations when it comes to ensuring that a swarm of autonomous agents (whether fully or partially automated) fulfill their tasks, while at the same time observing the rules of engagement. The project will explore the possibilities of command rather than control over such multi-agent systems. (The project suits someone who is eligible to work for Australian Defence).

Outlier detection in data streams

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.

Photonic-Atomic based Quantum Devices

We are developing microfabricated silicon nitride based photonic waveguides to interface with rubidium atoms as a platform for realising quantum devices.

This is an experimental physics project which includes fibre optics, photonics design work, microfabrication, atomic physics, and vacuum systems with the goal of advancing towards manufacturable devices.

Planning for aquaculture expansion under climate change

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.

Plasma modelling and simulation for magnetically confined fusion plasmas

A variety of projects are available in different modelling areas, with the focus applied to modelling a variety of important physics scenarios important to tokamak plasmas, such as those anticipated in ITER.

Point-of-care (POC) diagnostics

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.

Portable Instrument for Quantification and Genotyping of Waterborne Pathogens

Despite the tremendous efforts in developing effective on-site biosecurity and best management practices, waterborne parasites still cause significant health and economic burden worldwide. Early and rapid diagnosis together with an understanding of disease severity is critical for preventing parasite spread and enabling effective management strategies. Current routine diagnostic tests for waterborne parasites are not suitable for on-site detection. Shiddiky Laboratory is working on developing novel biosensing platform devices for the quantification and genotyping of waterborne parasites in surface and recreational waters. The device can be used to ensure improved waterborne parasite management, risk prediction, and rapid mitigation of impending outbreaks.

Precision-engineering of core-shell structures for prevention and treatment of diseases

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. Prof 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.

Privacy Attacks and Defences in Deep Neural Networks

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.

The expected outcomes include graph embedding methods for capturing real-world relationships in all their messiness and complexity. The anticipated contributions include impartial and accountable recommender models that are resistant to adversarial attacks and that slow the spread of misinformation.

Process-driven sediment regime changes in semi-enclosed tidal estuaries

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.

Binding of the antibodies to the antigens will activate the protein switch which will result in release of a signal.

Quantifying Australian aquaculture's environmental footprint

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.

Quantum causal models

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 Foundations and Quantum Causality

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.

Quantum machine learning for efficient quantum tracking

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 observers

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.

Quantum Program Verification

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.

It is to form the in-depth analysis of data-driven behaviors strongly interdependent with each other. Students will need to propose recommendation solutions for social network users and evaluate the prediction accuracy after applying the methods. Students will explore research issues to design the underlying models and algorithms for those heterogeneous and interdependent behavioral data to make predictions and recommendations, as well as develop software prototypes.

Safety Management Systems Differently: developing tools for safety practitioners of the new era

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.

Security of Industrial Internet of Things in Industry 5.0

With the emergence of the Internet of Things (IoT) and Industry 4.0, there is a trend for applying these services and applications in a large-scale industrial area. The IoT paradigm has changed the way of interactions with the things that surround us. In essence, the IoT promises ubiquitous connection to the Internet, turning common objects into connected devices. This project will review the different architectures of IIoT, and systematically study the security challenges associated with interoperability, access control, privacy, and trust-related issues, in general. The project will also identify the gaps in the state-of-the-art security techniques and requirements to determine the security services in the IIoT environment and propose potential mitigation techniques to address these gaps.

Segmentation of powerline corridors in complex environments

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.

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.

The project first studies how to discover and measure sensitive information of data instances, including features and labels, in data streams. It then investigates suitable models, schemes and mechanisms for effective protection of the sensitive information while preserving the required data utility. Finally it develops new techniques and methods for various privacy-preserving streaming data analysis and mining, including statistical analysis, association mining, classification and clustering, and evaluation of their performance.

This project will explore different innovative ways involving thrombosis for more effective treatment of cancers

The fusion of reinforcement learning and automated reasoning

This project explores the relationship between reinforcement learning (RL) and probabilistic model checking (PMC), as both are built upon the underlying model of Markov decision processes. On the one hand, PMC may be used to guide and constrain an RL agent when exploring optimal solutions so that the agent operates within a "safe region". On the other hand, RL may be used to improve the performance of model checking algorithms through statistical methods. We aim to improve the state-of-the-art of both worlds.

The rational use of simulators and training devices for training in transport industries

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?

The role of government in sustainable development and addressing climate change

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.

The use of minimally invasive biomarkers in the management of glioblastoma patients

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.

Theory of photonic quantum state generation and its use for cybersecurity

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.

Touch screen technology interaction in the flight deck

Flight decks are constantly evolving. New technology is constantly implemented in it to enhance safety. However, with such new additions there are also some challenges that might arise. These need to be understood to maintain safety. Touch screen technology is one of the newest additions in the flight deck. In this project, the interaction with such technology during various flying conditions will be explored. Any issues pilots might face when interacting with such technology will be understood. Training required to know when to use and when not to use touchscreen technologies will be examined too. As seen with many other types of flight deck technologies; a new piece of technology that starts off in the commercial airline industry might trickle down into the general aviation industry also. Hence, suitable recommendations will be made for the wider aviation industry.

Traditional Chinese medicine (TCM) and brain function

Many TCMs have a neuroprotective effect; that is, they protect the central nervous system against damage or degeneration due to diseases such as Parkinson’s disease. Working with TCMs with a known neuroprotective effect, we can isolate and identify the major constituents of selected TCM and test the compounds against cell-based models of Parkinson’s disease. By analysing and testing TCMs, we can determine their mechanism of action and develop new ways to treat neurological diseases.

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. 

Understanding and Resisting Adversarial Attacks in Deep Neural Networks

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.

Unveiling Backdoor Threats in Deep Neural Networks

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 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.

This project aims to research into the application of AI to assist with learning and teaching (L&T). There are many aspects of L&T that can benefit from the use of AI. However, instead of having AI playing a central role, e.g. run a class, this research focuses on the use of AI in a supporting role such as providing feedback to students, assist teachers in marking students work, or even directly mark student’s formative work etc. This applied research designs and develops AI tools to assist in specific L&T activities, applies these tools and evaluate the results. It explores the scenarios where AI tools are of benefit and determines how the tools should best be utilised.

Whale Economy – the value of whale watching to the Australian blue economy

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.

When Glyco meets Nano: Developing novel tools to explore complex glyco-interactions

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.

Validated assays will then be used to screen natural product libraries and start looking for the drugs of tomorrow.

This project will build on existing algorithms and apply deep learning to automatically identify various cyanobacteria species and their cell counts from microscopy images. A successful outcome would be extremely beneficial for several organizations, leading to more proactive management of toxic cyanobacteria blooms.

A previous experiment at the ANSTO Lucas Heights nuclear reactor investigated the possibility of neutrino flux altering the flow of time through weak force symmetry violation. This project would consist of analysing that data as well as modelling other situations (low energy solar neutrinos) where a time variation might be induced.

The Fast and The Furious Quantum Gates

Two qubit quantum gates are an essential building block to realising quantum computers. In trapped ion quantum computers these are presently limited by the vibrational confinement of the atoms, however there are proposed protocols which use strong optical forces to surpass this speed limit by using high intensity pulsed lasers. This project would investigate the spectroscopic limits of this approach for several common ions used in trapped ion quantum computing, with the goal of being able to bound the potential maximum fidelity of this approach.

Phototunable Nanophotonic Devices

Optical Metasurfaces, that is 2D arrays of sub-wavelength nanoresonators, have revolutionised the field of photonics by enabling compact, flat and versatile optical devices. The vast majority of optical metasurfaces are based on solid state materials like silicon or TiO2 which cannot be modified after fabrication. This project will explore the application of photoresponsive polymers to modulate the behaviour of optical metasurfaces. Nanoresonators are highly sensitive to surrounding refractive index, so small changes in the polymer property can have a significant effect on the light-matter interaction. In this project, optical metasurface will be coated with photoresponsive polymers, and spatial control over the refractive index will be explored using patterned optical stimulus. The final goal is to develop dynamic photonic devices driven by light.

Environmental sustainability challenges for the air transport industry

Aviation may be economically and socially sustainable but faces real environmental challenges. Globally, emissions from air travel need to be addressed in line with climate change advice from the Intergovernmental Panel on Climate Change (IPCC). There is a need to decarbonise the aviation industry and to move towards Net Zero Emissions (NZE), particularly when demand for international and domestic travel is gaining momentum. The PhD research could focus broadly on the relationship between aviation and climate change, whether mitigation or adaptation. It could alternatively focus on the characteristics of future sustainable air travel, the sustainability strategy of a particular airline or airport, the impact of new technologies (e.g. UAVS, eVTOL) on environmentally sustainable air travel, or the development alternative fuels such as SAF (Sustainable Aviation Fuel), hydrogen or electricity.

Managing waste in the built environment sector

A growing population and urbanisation have led to significant increases in the built environment needs and associated waste generation. There are calls for government and industry to develop better methods in managing waste across the built environment sector, including that from construction and demolition. There are the following strategic priorities: 1) Reducing the impact of waste on the environment, 2) Transitioning to a circular economy for waste, and 3) Building economic opportunity. The PhD research could focus broadly on the relationship between waste and the built environment, or be more specific on a particular built environment sector (e.g. buildings or transport) or waste type (e.g. from Construction & Demolition). It could be quantitative or qualitative in approach. The research could align closely with opportunities associated with the local Queensland Built Environment Waste Strategy and Action Plan, as well as construction around the Brisbane 2032 Olympic and Paralympic Games.

Engineered electron dynamics through controlled light-matter interactions

After absorption of a photon by a molecule an electron is elevated into an electronically excited state and follows the most favourable energetic pathway to either relax back to ground state (fluorescence) or undergo an intersystem crossing into a triplet state where it can initiate a chemical reaction or relax back to the ground state (phosphorescence). What if, instead of leaving these alternate pathways to chance, we could control the specific pathway the electron follows, by enhancing the electric field intensity at specific wavelengths or favour electron intersystem crossing processes with strong magnetic fields. This project will explore the engineering of electric and magnetic fields with dielectric nanoparticles and then bring organic molecules into close proximity and observe the resulting electron dynamics.

Quantifying the decline of Australia's common species

While global attention has rightly focused on the loss of threatened species, a critical gap exists in quantifying the decline of common species. Common species, often overlooked in conservation priorities, play foundational roles in ecosystems, ensuring the stability of food webs, nutrient cycling, and ecosystem services such as pollination and climate regulation. Yet, evidence shows that many of these once-abundant species are experiencing significant population declines due to habitat loss, climate change, pollution, and human activity. This project aims to investigate which species have declined, where this decline has occurred, and potential drivers of decline.

Spatially planning for the expansion of plantations

As the call to end native forest logging grows louder due to its detrimental impacts on biodiversity, carbon storage, and ecosystems, the transition to plantation-based timber production becomes a critical pathway. However, this shift demands more research into where we should expand plantations and how to manage them sustainably. Current knowledge gaps include identifying optimal locations for plantation expansion that minimize biodiversity loss and land-use conflicts while maximizing carbon sequestration. Equally important is developing sustainable management practices that avoid the pitfalls of monocultures, promote biodiversity within plantations, and maintain soil health and water quality.

Mapping the Path to Koala Recovery through the Great Koala National Park

The New South Wales Government’s commitment to creating the Great Koala National Park represents a landmark opportunity to reverse the rapid decline of koalas and protect their habitats. However, critical knowledge gaps remain regarding the spatial extent, specific locations, and conservation actions needed to halt koala extinction and put them on a path to recovery. This research project aims to provide a spatial plan to ensure the park’s success in conserving koalas. By mapping critical koala habitats and assessing threats such as deforestation, disease, and climate change, we will identify priority areas for protection, management and restoration. Additionally, we will evaluate the specific actions needed, such as habitat corridors, predator control, and disease management, to bolster koala populations. Beyond direct koala conservation, the Great Koala National Park offers substantial co-benefits that warrant quantification. These include enhanced biodiversity conservation by protecting habitats for other threatened species, increased carbon sequestration through forest preservation and restoration, and economic benefits from eco-tourism.

Charting Australia's Path to 30% by 2030

Australia’s commitment to protecting 30% of its land and sea areas by 2030, in line with global biodiversity targets, represents a crucial step toward halting biodiversity loss and restoring ecosystems. However, the roadmap to achieving this ambitious goal remains unclear. Critical questions about the location of new protected areas, the integration of Indigenous land management practices, and the economic and social implications of expanding protected areas need to be addressed through robust research. This research project aims to investigate the pathways for Australia to achieve the 30% by 2030 target by identifying priority areas for protection. A key focus will be on balancing biodiversity conservation with other land uses, such as agriculture, forestry, and urban development, to ensure the transition is equitable and sustainable.

Identifying Species at Risk of Losing All Habitats Due to Climate Change

Climate change is rapidly altering ecosystems, pushing many species to the brink of extinction as their habitats shrink or disappear entirely. However, a critical gap in our understanding remains: which species are most at risk of having no viable habitats in the future due to rising temperatures, shifting rainfall patterns, and other climate-related changes? This research aims to address this urgent question by identifying species likely to face complete habitat loss by the end of the century. Using advanced climate modeling, species distribution data, and habitat suitability analysis, we will predict which species will be unable to find suitable environments as climate change intensifies. This research will focus on species with narrow habitat ranges, specialized ecological needs, and limited dispersal abilities, which make them particularly vulnerable.
