Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project wi ....Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project will provide a new, yet crucial, perspective on how and why diseases spread. Our discoveries will help understand and manage the burden of infectious diseases from parasites in and beyond our cities and across the human-wildlife interface; essential for improving human and wildlife health in an increasingly urbanised Australia.Read moreRead less
E. coli as an indicator of faecal contamination in the Australian context. The goal of this research is to improve our ability to use Escherichia coli as an indicator of water quality by determining the extent to which non-faecal sources of E. coli contribute to coliform counts and to develop a method to differentiate non-faecal E. coli from those that are faecal derived.
The biology of arbovirus virulence and fitness in arthropod and vertebrate hosts in vivo. In Australia, Ross River virus (RRV) represents significant concern to human health. Between 1992-2005 more than 50,000 notifications of RRV infection have been reported. While not fatal, the disease is responsible for morbidity in the community/individual that can have both social and economic costs. The project has several national benefits. It will help elucidate whether there is any association between ....The biology of arbovirus virulence and fitness in arthropod and vertebrate hosts in vivo. In Australia, Ross River virus (RRV) represents significant concern to human health. Between 1992-2005 more than 50,000 notifications of RRV infection have been reported. While not fatal, the disease is responsible for morbidity in the community/individual that can have both social and economic costs. The project has several national benefits. It will help elucidate whether there is any association between RRV strain and increased risk of RRV transmission and/or occurrence of more severe cases of human disease. It will help develop technologies that can lead towards the identification of viral markers, which could provide new avenues in the design of novel antiviral strategies.

Biogeochemistry of ferruginous duricrusts. The project is focussed on the examination and application of microbial iron cycling in the formation of geologically stable, iron duricrusts in tropical regimes. The aim of the project is to develop a site-scale bioremediation strategy for iron ore mines by re-establishing canga, which are ‘ancient’ distinct ecosystems possessing unique plant species rarely found on Earth. This university-industry collaboration aims to produce economic benefits for the ....Biogeochemistry of ferruginous duricrusts. The project is focussed on the examination and application of microbial iron cycling in the formation of geologically stable, iron duricrusts in tropical regimes. The aim of the project is to develop a site-scale bioremediation strategy for iron ore mines by re-establishing canga, which are ‘ancient’ distinct ecosystems possessing unique plant species rarely found on Earth. This university-industry collaboration aims to produce economic benefits for the world’s iron mining industry through advanced training in mining-related research, and through the completion of the mining life cycle by site remediation, enhancing Australia’s position as a global leader in providing innovative solutions to today’s mining challenges.Read moreRead less
Understanding the koala microbiome: unlocking the secrets of koala health and dietary specialisation, and successful husbandry and translocation. This project aims to discover how the composition and function of koala gastrointestinal microbial communities differ in space and time in response to the varying nutritional quality and chemical composition of koala diets. Using detailed chemical analysis, cutting edge metagenomic and bioinformatic pipelines and powerful approaches to study enzyme fun ....Understanding the koala microbiome: unlocking the secrets of koala health and dietary specialisation, and successful husbandry and translocation. This project aims to discover how the composition and function of koala gastrointestinal microbial communities differ in space and time in response to the varying nutritional quality and chemical composition of koala diets. Using detailed chemical analysis, cutting edge metagenomic and bioinformatic pipelines and powerful approaches to study enzyme functions in the koala’s gut, the investigators aims to reveal the role of microbes in detoxification of plant toxins and degradation of recalcitrant fibre fractions. The outcomes aim to facilitate the use of faecal transplants to improve digestive function for translocated and rehabilitated koalas, enhancing options for koala management and conservation.Read moreRead less
Formation and stabilisation of coastal blue carbon. Blue carbon is organic carbon stored within coastal vegetated ecosystems. This project will examine the composition, formation and dynamics of blue carbon in a range of coastal ecosystems. Combining advanced analytical chemistry with environmental microbiology, we will discover how blue carbon is stabilised and destabilised, a critical factor in nature-based climate change mitigation strategies. Further, we will gain a quantitative understandin ....Formation and stabilisation of coastal blue carbon. Blue carbon is organic carbon stored within coastal vegetated ecosystems. This project will examine the composition, formation and dynamics of blue carbon in a range of coastal ecosystems. Combining advanced analytical chemistry with environmental microbiology, we will discover how blue carbon is stabilised and destabilised, a critical factor in nature-based climate change mitigation strategies. Further, we will gain a quantitative understanding of blue carbon contributions to carbon cycling, providing enhanced modeling and prediction of climate-cycle feedbacks in response to biotic and environmental change. This research will significantly benefit Australia’s effective management of coastal vegetated ecosystems for maximum carbon offsets.Read moreRead less
Smart management of disinfectant in chloraminated water-supply systems. Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems.

Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems. While chloramine delivers microbiologically safe drinking water in warmer climates and in long distribution systems, it is largely unpredictable, costs water utilities millions of dollars annually, and has uncertain benefits. This project’s control system will be guided by quantitative models formulated from multi-pronged, fundamental experiments. The project will quantify microbial chloramine decay and determine mechanisms to increase predictability. The project will develop and demonstrate a real-time control technology which delivered microbiologically safe, cost-efficient drinking water to people in warmer climates, despite warming climate and increasing population.Read moreRead less
