Nanoengineered gradient substrata as a novel approach for understanding infection mechanisms. This project will advance our understanding of how bacteria colonise surfaces and will also inform the development of novel antibacterial coatings and diagnostic tools for device-associated infections, which have a significant impact on patients and are a huge burden to the healthcare system.
Rapid Pathogen Detection using Super-Sensitive Multiplexing Nanophotonic Probes. Responding to an urgent need to advance rapid molecular diagnostics, this project aims to explore new photonics and biochemistry approaches to DNA recognition. It is anchored on proprietary light-emitting nanodots which have single-molecule sensitivity in conjunction with tunable optical identities. The project aims to develop a multiplexing reagent library of DNA probes to sense trace DNA molecules and to recognise ....Rapid Pathogen Detection using Super-Sensitive Multiplexing Nanophotonic Probes. Responding to an urgent need to advance rapid molecular diagnostics, this project aims to explore new photonics and biochemistry approaches to DNA recognition. It is anchored on proprietary light-emitting nanodots which have single-molecule sensitivity in conjunction with tunable optical identities. The project aims to develop a multiplexing reagent library of DNA probes to sense trace DNA molecules and to recognise multiple pathogens in a single assay. This innovation aims to create a hybrid-Polymerase Chain Reaction (PCR) technology platform for current industry-standard pathogen detection tests. The outcomes of the project aim to enable DNA based pathogen diagnostics within 90 minutes, four times faster than the current tests.Read moreRead less

Mucus control: Applying concepts from bacteriophage-mucus interactions. This project aims to examine how mucus-adherent bacteriophage interact with bacteria in mucus as a mechanism to manipulate microbiomes. Bacterial infections at mucosal surfaces in animals are a serious global health threat. Traditionally antibiotics have been used to curb mucosal infections, but antibiotic resistance means new therapies are urgently needed. Bacteriophage – viruses that infect bacteria – can kill bacteria and ....Mucus control: Applying concepts from bacteriophage-mucus interactions. This project aims to examine how mucus-adherent bacteriophage interact with bacteria in mucus as a mechanism to manipulate microbiomes. Bacterial infections at mucosal surfaces in animals are a serious global health threat. Traditionally antibiotics have been used to curb mucosal infections, but antibiotic resistance means new therapies are urgently needed. Bacteriophage – viruses that infect bacteria – can kill bacteria and might provide a layer of antimicrobial immunity in animal mucus. The anticipated outcomes are resolving how bacteriophage control bacteria within mucus, and applying concepts to bioengineer mucosal microbiomes.Read moreRead less
Bioactive Peptides as Pharmacological Tools and Novel Drug Leads. Bioactive peptides are produced by all organisms and play numerous critical physiological roles, including in cellular communication, host defence and capture of prey. Peptides have huge potential as tools for studying roles of signalling pathways and as novel drugs due to their high affinity and selectivity for various therapeutically relevant targets. However their use has been limited by poor in vivo stability. This project is ....Bioactive Peptides as Pharmacological Tools and Novel Drug Leads. Bioactive peptides are produced by all organisms and play numerous critical physiological roles, including in cellular communication, host defence and capture of prey. Peptides have huge potential as tools for studying roles of signalling pathways and as novel drugs due to their high affinity and selectivity for various therapeutically relevant targets. However their use has been limited by poor in vivo stability. This project is focused on studying structural features of a range of peptides and their contributions to both activity and to resistance against degradation, with the aim to develop stabilised bioactive peptide sequences for in vivo applications, allowing the full potential of peptides as drugs to be realised.Read moreRead less
Convergence of biomaterials and immunology: a technology platform for delayed burst release of vaccines. A large challenge in vaccination, particularly in wildlife such as for the growing problem of Chlamydia in koalas, is to provide the necessary booster shots. This project will develop implants that will be inserted under the skin at the time of the first shot, and will spontaneously burst later to release the booster shot to provide protection.
Mathematical and statistical methods for modelling invivo pathogen dynamics. This project aims to develop mathematical models and Bayesian statistical methods that better capture how natural defence responses and drugs help control infection. When viruses (e.g. influenza) or parasites (e.g. malaria) invade the human body, they begin to replicate. To date, only simple mathematical models have been developed to capture these processes, and these models are not well formulated. This project will im ....Mathematical and statistical methods for modelling invivo pathogen dynamics.

When viruses (e.g. influenza) or parasites (e.g. malaria) invade the human body, they begin to replicate. To date, only simple mathematical models have been developed to capture these processes, and these models are not well formulated. This project will improve biomathematics and biostatistical algorithms for pathogen dynamics and is ultimately expected to benefit public health and clinical research aimed at alleviating the effect of infectious diseases on human health.Read moreRead less

Mathematical and statistical modelling of antimalarial drug action. This project aims to develop a mathematical model to optimise global antimalarial treatment policy. Malaria-causing parasites are resistant to the most potent antimalarial drug available. If left unaddressed, a catastrophic rise in global malaria incidence and mortality could occur. Changes to global antimalarial treatment policy increasingly rely on mathematical models, but they do not encompass recent breakthroughs in antimala ....Mathematical and statistical modelling of antimalarial drug action. This project aims to develop a mathematical model to optimise global antimalarial treatment policy. Malaria-causing parasites are resistant to the most potent antimalarial drug available. If left unaddressed, a catastrophic rise in global malaria incidence and mortality could occur. Changes to global antimalarial treatment policy increasingly rely on mathematical models, but they do not encompass recent breakthroughs in antimalarial drug action and the immune response. This project’s model is expected to improve antimalarial drug dosing regimens and control the spread of antimalarial drug resistance.Read moreRead less
Broad spectrum nanomedicine for Meningitis treatment. Brain inflammatory diseases are among the top ten infectious causes of death. The project aims to provide Australian doctors with a superior alternative of treating infections that do not respond to conventional antibiotics. The nanomedicine developed will reduce the burden of hospital and boost Australia economy in the biomedical sector.
An interdisciplinary approach to host-pathogen interactions in infection. This project aims to understand the molecular and cellular interactions between host and parasite, as well as providing a quantitative framework for analysing infection dynamics in other systems. Infection involves a complex interaction between the host and the parasite, which is very dynamic and therefore difficult to study by traditional sampling and analysis approaches. This project has combined mathematical modelling w ....An interdisciplinary approach to host-pathogen interactions in infection. This project aims to understand the molecular and cellular interactions between host and parasite, as well as providing a quantitative framework for analysing infection dynamics in other systems. Infection involves a complex interaction between the host and the parasite, which is very dynamic and therefore difficult to study by traditional sampling and analysis approaches. This project has combined mathematical modelling with a novel experimental protocol to allow the study of kinetics of parasite replication in vivo. Expected outcomes will provide significant benefits, such as new avenues for vaccination and immune intervention.Read moreRead less
