The Australian Centre for Complex Systems brings together leading researchers from several disciplines and institutions to conduct research on questions fundamental to understanding and managing complex systems. Its core research program, based on the theme of computation in and by networks of agents, has two interwoven strands. The science strand addresses questions about emergent properties, natural computation, and nonlinear dynamics. The engineering strand addresses issues about methodology, modelling toolkits, and management and control. Practical applications are advanced via collaborative projects that address key issues in biology, environment, and socio-economics.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
Traversing a treacherous landscape: Modelling caterpillar movement and behaviour on whole plants at multiple scales. 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 ....Traversing a treacherous landscape: Modelling caterpillar movement and behaviour on whole plants at multiple scales. 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.

MOLECULAR BREEDING OF CYTOCHROME P450 ENZYMES. Cytochrome P450s are enzymes that catalyse an impressive array of oxidative transformations. However, there is little available data on how to modify their substrate specificity and generate tailored biocatalysts. We plan to use an emerging technology known as DNA shuffling to create libraries of P450s with varying activities. These will then be screened for enzymes that can catalyse the formation of indigo (a blue dye) and indirubin (a chemother ....MOLECULAR BREEDING OF CYTOCHROME P450 ENZYMES.

We plan to use an emerging technology known as DNA shuffling to create libraries of P450s with varying activities. These will then be screened for enzymes that can catalyse the formation of indigo (a blue dye) and indirubin (a chemotherapeutic agent). The enzymes that catalyse indigo formation will be useful in the production of coloured transgenic plants and those that produce indirubin will have a role in gene therapy.Read moreRead less

The cytochrome P450s (P450s) are a family of enzymes that are perhaps the most versatile biological catalysts known. DNA shuffling is an emerging technique that takes the genes encoding families of enzymes and creates libraries of catalysts with both improved and novel properties. We will obtain proof of concept that shuffled P450 libraries can be screened and optimized for use as biocatalysts in drug development. The methodologies developed here will overcome two critical bottlenecks in current drug development: the optimisation and metabolic profiling of new drug candidates. This will yield important benefits in accelerating the optimisation and safety testing of drugs under development.Read moreRead less
Organophosphate pesticide degradation: evolved enzymes and biomimetics for bioremediation and medicine. Organophosphate (OP) pesticides are an indispensable part of modern agriculture - their use results in dramatically increased crop yields. However, they are toxic and can damage the environment and cause significant health problems. Enzymes are currently being used to treat runoff water that is contaminated with OPs.

Organophosphate (OP) pesticides are an indispensable part of modern agriculture - their use results in dramatically increased crop yields. However, they are toxic and can damage the environment and cause significant health problems. Enzymes are currently being used to treat runoff water that is contaminated with OPs. The same enzymes also have the potential to aid in the treatment of OP poisoning. However, OP degrading enzymes could be improved in many ways - we will evolve these enzymes to enhance their catalytic properties - to enable them to act more efficiently on an increased number of OPs.

Agriculture is an important economic activity in Australia that results in considerable export revenues. Two of the major problems facing agriculture around the globe are the incidence of diseases and the scarcity of water. Agricultural losses caused by plant pathogens and low water availability account for billions of dollars every year and have profound economic and social implications. Water is an extremely scarce resource in Australia and periodic droughts inflict immense losses to the Australian agricultural sector. Our research will explore new and cleaner strategies to provide crop protection as well as to increase water use efficiency.Read moreRead less
