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
Understanding the dynamics of malaria infection. Malaria infection kills around one million patients each year and this project involves an interdisciplinary team who will directly measure how the parasite grows and is killed by the immune system. A better understanding of parasite growth and control will help develop better drugs therapy and vaccination for this important infection.
Screening platforms for malaria drug discovery: identification of new therapeutics. Innovative image based technologies will be developed to identify molecules which stop malaria parasite growth and its transmission to the mosquito host. As more resistance is emerging against the current drugs of choice, new molecules acting through different mechanisms are urgently needed.
Translating pharmacokinetic and pharmacodynamic data to better design new drugs for the treatment of Trypanosoma cruzi infection. New drugs to treat T. cruzi infection are urgently needed, however their design has been hampered by an incomplete understanding of complex host-parasite interactions, inadequate in vitro and in vivo tools to rigorously define activity during drug discovery, and a poor appreciation of concentration/effect relationships. This project aims to develop new and much needed ....Translating pharmacokinetic and pharmacodynamic data to better design new drugs for the treatment of Trypanosoma cruzi infection. New drugs to treat T. cruzi infection are urgently needed, however their design has been hampered by an incomplete understanding of complex host-parasite interactions, inadequate in vitro and in vivo tools to rigorously define activity during drug discovery, and a poor appreciation of concentration/effect relationships. This project aims to develop new and much needed in vitro methods to better define the kinetic and dynamic activity of new drug candidates, and will provide a rational basis for translating this information into lengthy animal models of T. cruzi infection. The outcome aims to be rationally designed drug candidates that are available in a shorter period of time and are suitable for further development.Read moreRead less

Summary
Understanding how bacteria become sticky. This study will investigate the machinery used by bacteria to build specialised sticky fibres which allow them to attach to surfaces. The outcomes will significantly advance our understanding of how bacteria generate molecular weapons enabling them to survive and to infect humans and animals.
How auto-transporter proteins mediate bacterial interactions. This project aims to investigate the structure-function relationships that underpin key auto-transporter roles in bacterial cell adhesion, aggregation and biofilm formation. Auto-transporter proteins are extremely common in bacteria where they play a central role in controlling bacterial interactions with other bacteria, with human cells, and with surfaces. This project will define the molecular mechanisms underlying these processes. ....How auto-transporter proteins mediate bacterial interactions.

Auto-transporter proteins are extremely common in bacteria where they play a central role in controlling bacterial interactions with other bacteria, with human cells, and with surfaces. This project will define the molecular mechanisms underlying these processes. This will have significant benefits, such as providing the basis for the development of approaches to block auto-transporter functions that contribute to the establishment of persistent and difficult to treat bacterial infections.Read moreRead less

New drugs against parasitic nematodes of livestock animals. This project aims to develop an innovative technology platform to deliver novel anti-infectives as biotechnological outcomes, using postgenomics, computing and chemistry. Advanced molecular, computer and chemistry technologies provide unprecedented opportunities to design radically new interventions against socioeconomically important infectious diseases affecting billions of animals worldwide. Anticipated outcomes are the design of radically new chemotherapies to control parasitic diseases, the translation of fundamental research into biotechnological outcomes, international visibility of Australian science, and a solid skills- and knowledge-base in veterinary drug development.Read moreRead less
Combating invading DNA: a process conserved in evolution? Cells of our body defend against foreign genetic material, or DNA, which indicates an infection or invading DNA capable of causing mutation. These defences are so important that several layers have developed during evolution, and this project compares the responses of different organisms to foreign DNA.
Epigenetic regulation in bacteria. This project aims to understand the effect of DNA modification on gene regulation in the bacterial organism Escherichia coli, which causes urinary tract infection worldwide. High-throughput DNA sequencing technologies mean one can determine the entire genetic blueprint of a bacterium – its genome – accurately, quickly and cheaply. Single-molecule real-time sequencing provides a complete read-out of a bacterial genome (genetic data) and chemical modifications of ....Epigenetic regulation in bacteria. This project aims to understand the effect of DNA modification on gene regulation in the bacterial organism Escherichia coli, which causes urinary tract infection worldwide. High-throughput DNA sequencing technologies mean one can determine the entire genetic blueprint of a bacterium – its genome – accurately, quickly and cheaply. Single-molecule real-time sequencing provides a complete read-out of a bacterial genome (genetic data) and chemical modifications of the DNA (epigenetic data). Epigenetic data can affect regulation: how genes are switched off and on. This project seeks to harness the power of single-molecule DNA sequencing, together with state-of-the-art genomic and molecular approaches, to better understand the impact of DNA modification on gene regulation in the model bacterial organism, Escherichia coli. This work will support advanced training in bioinformatics and microbiology and improve our understanding of regulation in all bacteria.Read moreRead less
Mathematical modelling can provide vital information on the effectiveness and practical implementation of microbicides and vaccines against HIV. This project will produce mathematical models of the earliest stages of HIV infection suitable for investigation of the implementation of vaccines and microbicides. It will provide a framework to investigate why these interventions have performed poorly to date, and how these may be better implemented.
