This project is focused on understanding the interaction of cold atmospheric plasmas with biofilms, with the aim of biofilm eradication and ultimately offering an environmentally friendly alternative to current detergents and antibiotics. The research expects to elucidate the fundamental mechanisms of action for breakthrough plasma intervention technologies, which are sufficiently active to cope with the resistant nature of biofilms, yet are of low energy, do not adversely affect surface properties and critically leave no residual chemistry. This should provide significant benefits by delivering a new method to tackle the ubiquitous problem of biofilm contamination in food, water and medical areas.Read moreRead less
Genetic Basis of Variable Expression of Glycan Xeno-Autoantigens by Cattle. Meat and dairy products from cattle contain sugar structures (glycans) that are not made by humans. These structures can be recognised by the immune system and lead to allergic reactions, inflammation and potentially cancer. These non-human structures are called xeno-autoantigens or XAs. We have discovered individual cattle that do not produce one of these XAs. We will study the gene required to make XA in the XA-free ca ....Genetic Basis of Variable Expression of Glycan Xeno-Autoantigens by Cattle. Meat and dairy products from cattle contain sugar structures (glycans) that are not made by humans. These structures can be recognised by the immune system and lead to allergic reactions, inflammation and potentially cancer. These non-human structures are called xeno-autoantigens or XAs. We have discovered individual cattle that do not produce one of these XAs. We will study the gene required to make XA in the XA-free cattle to find the underlying mutation. The same approach will be used to look for natural XA-free individuals in other food species. This knowledge may enable us to create a test to facilitate the natural breeding of non-GMO, XA-free livestock to benefit Australian primary producers and provide safer food for consumers.Read moreRead less
Mathematical models of diseases with complex transmission routes. This project aims to model diseases that spread via a mixture of routes including food, water, the environment, and direct spread between individuals. Key diseases include: avian influenza, which causes massive disruption to the poultry industry; gastroenteritis, which costs Australia $1,250 million each year; and leptospirosis, which causes one million severe illnesses each year globally. This project will develop mathematical a ....Mathematical models of diseases with complex transmission routes.

Key diseases include: avian influenza, which causes massive disruption to the poultry industry; gastroenteritis, which costs Australia $1,250 million each year; and leptospirosis, which causes one million severe illnesses each year globally. This project will develop mathematical and statistical tools to better estimate risk, analyse outbreak data, and provide guidance for disease control. This research will improve policy and enhance our ability to respond to disease outbreaks.Read moreRead less
Combating fungal biofilm growth on surfaces. This project aims to establish a scientific basis for the design and development of thin coatings, for use on biomedical devices, that can resist the attachment of fungal cells and the ensuing formation of infectious fungal biofilms on their surfaces. Advancing mechanistic understanding of how physico-chemical properties of materials surfaces influence fungal attachment will enable rational development and optimisation of coating chemistries and struc ....Combating fungal biofilm growth on surfaces. This project aims to establish a scientific basis for the design and development of thin coatings, for use on biomedical devices, that can resist the attachment of fungal cells and the ensuing formation of infectious fungal biofilms on their surfaces. Advancing mechanistic understanding of how physico-chemical properties of materials surfaces influence fungal attachment will enable rational development and optimisation of coating chemistries and structures. Tethered antifungal compounds will be added to polymer surfaces by controlled polymerisation methods to provide active deterrence; factors such as conformational flexibility will be studied to optimise coatings, which may will prevent life-threatening infections and reduce healthcare costs.Read moreRead less

This project aims to characterise the genetic basis for the production of tetrodotoxin; a potent neurotoxin of ecological and biomedical significance. We hypothesise that tetrodotoxin is produced by microorganisms and transferred via the food web to fish, molluscs and other marine animals. Our integrated genomic and synthetic biology approach, targeting key biosynthesis genes, will reveal pathways for the production of tetrodotoxin and other potentially valuable compounds. In addition to providing unprecedented insight into the ecology and biosynthesis of this enigmatic toxin, the data generated will enable improved management of seafood safety and provide a foundation for the future development of novel neuroactive compounds.Read moreRead less
Understanding and controlling bioavailability: passive dosing of persistent organic pollutants into recombinant cell bioassays. Bioassays with mammalian cell lines may replace animal testing in chemical risk assessment if issues with limited sensitivity can be overcome for very hydrophobic chemicals such as polychlorinated dibenzodioxins. The project will solve this problem by developing a polymer-release dosing technique that assures defined and constant exposure.

Current phytoplankton ecological theory is derived primarily from lab cultures, but in nature phytoplankton have unique microbiomes that support their growth and ongoing ocean primary production. This project aims to establish the structure and function of these natural microbiomes, and how they contribute to seafood poisoning caused by bacteria and algal biotoxins. Using advanced flow cytometry with single-cell microbial profiling, we will sample nano-scale plankton microbiomes and synthetic microbiome phylogenomics to the link between microbiomes and seafood poisoning outbreaks. The outcomes will underpin enhanced predictive modelling of seafood risk to ensure the safety and export security of Australia's $2 billion seafood industry.Read moreRead less

The project aims to greatly improve the accuracy and scope of computational epidemiological models predicting emergence and evolution of foodborne diseases in Australia. It expects to reveal key pathways for both biological evolution of microorganisms, and their spread though food supply chains and human interactions. The intended outcomes include discovering how the most dominant strains of foodborne infection emerge and self-organise in complex networks, how to predict and contain the epidemics closer to their source, and which are the most vulnerable groups and communities. This should make a significant economic and social impact, improving health of the population, while also safeguarding national and international supply chains.Read moreRead less
