Understanding mutation and genetic reassortment in viruses: new mathematical models of viral dynamics and evolution. This project aims to understand how evolutionary processes and ecological conditions combine to ignite and sustain viral epidemics. Using novel mathematical models and statistical methods we will study the manner in which viral genes mutate and are recombined, as well as the rates of these important forces.
Optimising disease surveillance to support decision-making. COVID-19 has demonstrated the critical role of epidemic data and analytics in guiding government response to pandemic threats, reducing disease and saving lives. The demand for epidemic analytics for response to threats of national significance will only grow. The goals of this project are to 1) determine the combination(s) of surveillance methods that provide the most useful data for epidemic analysis and 2) translate these findings in ....Optimising disease surveillance to support decision-making. COVID-19 has demonstrated the critical role of epidemic data and analytics in guiding government response to pandemic threats, reducing disease and saving lives. The demand for epidemic analytics for response to threats of national significance will only grow. The goals of this project are to 1) determine the combination(s) of surveillance methods that provide the most useful data for epidemic analysis and 2) translate these findings into the blueprint for a next-generation infectious disease surveillance system for Australia. We will use a simulation-evaluation approach, coupling methods from infectious disease modelling with those from information theory optimal design. Outcomes will enable more tailored and effective pandemic response.Read moreRead less
Do insect-specific flaviviruses regulate the transmission of mosquito-borne diseases in Australia? Mosquito-borne viral diseases such as dengue occur in Australia. The research team recently discovered related viruses in mosquitoes from Darwin that do not infect humans, but may inhibit the spread of viral diseases by mosquitoes. This project will investigate the life cycles of these new viruses to understand how they affect the spread of viral diseases by mosquitoes.
Upper Gastrointestinal Function And Glycaemic Control In Diabetes Mellitus

Summary
There is now increasing recognition that the stomach and intestines, by regulating the absorption of nutrients into the body and by releasing hormones that enhance insulin secretion, play a central role in the control of blood glucose in diabetes mellitus. We seek to understand the nature and causes of disturbed gut function in diabetes, so that we can optimise dietary and drug strategies to prevent and treat this condition.
Microbial natural history and molecular evolution. This project aims to develop mathematical and computational models of microbial evolution that capture dynamics at both within-host and between-host scales, combined with processes of mutation. Integration of these elements with computational statistical methods will produce a framework that will enable inference from genome sequencing data. The mathematical models will be applied to bacterial genomic data to investigate how natural selection ac ....Microbial natural history and molecular evolution. This project aims to develop mathematical and computational models of microbial evolution that capture dynamics at both within-host and between-host scales, combined with processes of mutation. Integration of these elements with computational statistical methods will produce a framework that will enable inference from genome sequencing data. The mathematical models will be applied to bacterial genomic data to investigate how natural selection acts on experimental and natural populations of microorganisms. The mathematical models and statistical approaches developed here are intended to be applicable to infectious disease of both humans and domesticated animals, and could influence public health policies.Read moreRead less
Immunomodulatory Molecules Of Parasitic Helminths As Novel Therapeutics For Allergic Disorders.

Summary
Australia has one of the highest rates of asthma in the world with almost 3 million Australians are affected by this disease. Previous research has shown that infection with various types of parasitic worms lessens the severity of asthma. The aim of this research is to find out why this happens and to isolate the ingredients from the parasite that suppress asthma. Once found, these molecules can be used to create new drugs for the prevention of asthma and allergies in children and adults.
Targeting The Human Immune Response To Bacterial Superantigens.

Summary
This research investigates the human immune response to infection with toxin producing bacteria. Toxins activate the human immune system which can lead to serious illness or the development of disease that can progress rapidly and be associated with high rates of morbidity and mortality. Investigating the harmful effects of infection with toxin producing bacteria in humans and the damage caused by their toxins is essential for the development of effective therapeutic strategies.
