In this respect, the project is a premier example of the priority goal Breakthrough Science and of the national research priority Frontier Technologies.Read moreRead less
Genetic variation of transcriptional control. Genetic variation is a key cause phenotype differences in humans, animals, and plants and so of great economic importance. Despite its proven importance to human diseases, ?quantitative? variation in the amount of gene expression rather than ?qualitative? protein sequence changes, has not been systematically studied. We have developed a powerful method to identify genetic causes of quantitative variation using crosses of inbred mice in conjunction wi ....Genetic variation of transcriptional control. Genetic variation is a key cause phenotype differences in humans, animals, and plants and so of great economic importance. Despite its proven importance to human diseases, ?quantitative? variation in the amount of gene expression rather than ?qualitative? protein sequence changes, has not been systematically studied. We have developed a powerful method to identify genetic causes of quantitative variation using crosses of inbred mice in conjunction with microarray techniques to analyse expression of thousands of genes simultaneously. These studies will be extended to humans and be significant to wide areas of biological and commercial activity.Read moreRead less
Topological Approaches for Three Dimensional Graph Drawing. Human analysis of huge quantities of relational data in biotechnology, web engineering, social networks, and computer networks requires visualization. In recent years, three-dimensional visualisation has promised to give new insights into such abstract data.

Human analysis of huge quantities of relational data in biotechnology, web engineering, social networks, and computer networks requires visualization. In recent years, three-dimensional visualisation has promised to give new insights into such abstract data. However the past ten years of visualization research has had very little impact on the industry; visualization software providers have not adopted visualization methods developed by academics. We hypothesise that current 3D relational visualization methods fail because they do not pay attention to the human perception of topology. In this project we will leverage mathematical topology to construct new methods for the 3D visualization of relational data.

Behaviour of large networks of neurons in a functioning organ: a realistic computer-based model of the enteric nervous system. The organisation of the gut nervous system is well understood, but how nerve cells cooperate to control gut movements and secretions are matters of conjecture. We will test these conjectures by simulating the behaviour of the gut nervous system using an anatomically and physiologically realistic computer model to predict the way the gut responds to specific stimuli and t ....Behaviour of large networks of neurons in a functioning organ: a realistic computer-based model of the enteric nervous system. The organisation of the gut nervous system is well understood, but how nerve cells cooperate to control gut movements and secretions are matters of conjecture. We will test these conjectures by simulating the behaviour of the gut nervous system using an anatomically and physiologically realistic computer model to predict the way the gut responds to specific stimuli and test these predictions using novel methods for recording gut movements and nervous activity. This will provide the first complete description of how a mammalian nervous system generates complex behaviours and will provide substantial pointers to how other nervous systems achieve similar tasks.Read moreRead less

By understanding the regulatory potential of microRNA molecules, we will understand more about species diversity, regulatory networks, and plant and animal development. The early adoption of multi-gigabase next-generation sequencing technology in Australia provides rare and exciting opportunity to lead the world in genome-scale research, and to ensure that Australia has the necessary skill base to remain internationally competitive in this field.Read moreRead less
The prediction of sleep/wake behaviour based on physiological and social factors. The prevalence of shiftwork has increased in Australia over the last few decades. Shiftworkers obtain less sleep, have greater difficulty maintaining good relationships, have poorer health, and are more likely to be injured at work than others. Using the largest dataset of its kind, we will substantially contribute to understanding the relationships between work hours, sleep, performance and safety. Ultimately, the ....The prediction of sleep/wake behaviour based on physiological and social factors. The prevalence of shiftwork has increased in Australia over the last few decades. Shiftworkers obtain less sleep, have greater difficulty maintaining good relationships, have poorer health, and are more likely to be injured at work than others. Using the largest dataset of its kind, we will substantially contribute to understanding the relationships between work hours, sleep, performance and safety. Ultimately, the project will answer a question critical to workplace safety - how much time off between shifts is needed to be alert and safe at work? The project will also produce tools to help industry design fatigue-friendly rosters, improving the safety, productivity and general well-being of shiftworkers in Australia and overseas.Read moreRead less

How caterpillars move on plants and where they feed is central to developing plants resistant to these insect pests. Our research program will generate computer models of caterpillar behaviour on virtual plants that interact in realistic ways with the changing structure of the plant as it grows, its micro-architecture and environment. We provide a set of tools that will form the cornerstone of important future research agendas in the ecology of foraging caterpillars, optimisation of insecticide spray application, and the development of novel genetically transformed plants for insect control central to the future of Australian agriculture.

Emergence of robust, stable structures via computation within natural networks. An ever-increasing challenge for modern society is the sheer complexity of vast infrastructures. Unexpected, and sometimes catastrophic, behaviour often emerges from interactions between elements of large systems.
