A Novel Geometric Approach to Shocks in Reaction-Nonlinear Diffusion Models. Reaction-nonlinear diffusion models play a vital role in the study of cell migration and population dynamics. However, the presence of aggregation, or backward diffusion, leads to the formation of shock waves - distinct, sharp interfaces between different populations of densities of cells - and the breakdown of the model. This project will develop new geometric methods to explain the formation and temporal evolution of ....A Novel Geometric Approach to Shocks in Reaction-Nonlinear Diffusion Models. Reaction-nonlinear diffusion models play a vital role in the study of cell migration and population dynamics. However, the presence of aggregation, or backward diffusion, leads to the formation of shock waves - distinct, sharp interfaces between different populations of densities of cells - and the breakdown of the model. This project will develop new geometric methods to explain the formation and temporal evolution of these shock waves, while simultaneously unifying existing regularisation techniques under a single, geometric banner. It will devise innovative tools in singular perturbation theory and stability analysis that will identify key parameters in the creation of shock waves, as well as their dynamic behaviour.Read moreRead less
The mechanochemical basis of cell polarity. This project aims to study how epithelial cells initiate polarisation, a major question in biology that conventional biochemical, cell biological and genetic approaches have not answered. This project will investigate the mechanochemical basis of symmetry breaking in the cellular cortex, a thin layer of actomyosin filaments underneath the plasma membrane, and how this forms signalling zones. Understanding polarity is expected to improve epithelia manip ....The mechanochemical basis of cell polarity.

Understanding the mechanism of two important cytochrome P450 catalysed reactions: dehydrogenation and C-C cleavage. Cytochromes P450 are enzymes that play key roles in drug metabolism and biosynthesis. P450s often catalyse hydroxylation but also carry out important transformations such as dehydrogenation or carbon-carbon bond cleavage. Such reactions are pivotal in many biological pathways. This work will elucidate the mechanism of these transformations and the factors that facilitate their occu ....Understanding the mechanism of two important cytochrome P450 catalysed reactions: dehydrogenation and C-C cleavage. Cytochromes P450 are enzymes that play key roles in drug metabolism and biosynthesis. P450s often catalyse hydroxylation but also carry out important transformations such as dehydrogenation or carbon-carbon bond cleavage. Such reactions are pivotal in many biological pathways. This work will elucidate the mechanism of these transformations and the factors that facilitate their occurrence. This will mainly entail the synthesis of small organic mechanistic probes and determining the structure and stereochemistry of the product of enzymic oxidation. Understanding these mechanisms will allow us to predict when such reactions will occur, enabling their utilisation in for example drug design in the avoidance of the formation of toxic metabolites.Read moreRead less

Estimated economic cost of cyanobacteria blooms to Australia are at $150 million p.a. Early warning for cyanobacteria blooms will inform water managers to conduct preventive and operational control in reservoirs and water works, and significantly lower risks for public health and costs for monitoring and treatment. Resulting early warning systems will be novel prototypes for cyanobacteria blooms in drinking water reservoirs based on forecasting models adaptable to environmental and climate change. Model-based scenario analysis will also assist in informed decisions on effects of drought, injection of recycled water and global warming to cyanobacteria growth.Read moreRead less

The diverse roles of ion channels include action potential generation, control of ion flow across secretory and epithelial cells, and regulation of cell volume, motility and proliferation. Pharmacological modulators are powerful tools for probing ion channel function, but for most channels these tools are lacking. Thus, this p .... Electrophysiology Platform for Ion-channel Characterisation. Ion channels are ubiquitous pore-forming membrane proteins, with the human genome encoding >300 ion channels. The diverse roles of ion channels include action potential generation, control of ion flow across secretory and epithelial cells, and regulation of cell volume, motility and proliferation. Pharmacological modulators are powerful tools for probing ion channel function, but for most channels these tools are lacking. Thus, this project aims to develop the first comprehensive toolbox of ion channel modulators using an integrated in vitro/in vivo electrophysiology platform. These pharmacological tools will be made freely available to the Australian research community for probing the mechanism and physiological function of ion channels.Read moreRead less
Unravelling the principles of bilateral brain wiring. This project seeks to investigate the molecular principles of brain wiring in mammals and how small changes can generate complex outcomes. Neurons in the mammalian brain must be precisely wired together for the brain to function correctly. The project aims to identify the molecular and cellular rules governing commissural wiring in the mammalian cortex to determine how the largest fibre tract in the human brain, the corpus callosum, evolved. ....Unravelling the principles of bilateral brain wiring. This project seeks to investigate the molecular principles of brain wiring in mammals and how small changes can generate complex outcomes. Neurons in the mammalian brain must be precisely wired together for the brain to function correctly. The project aims to identify the molecular and cellular rules governing commissural wiring in the mammalian cortex to determine how the largest fibre tract in the human brain, the corpus callosum, evolved. This may have involved modifications in mechanisms affecting axon guidance that differ between placentals and marsupials. The project investigates the regulatory gene networks determining commissural neuron fate, the regulation of axon guidance components, and the influence of surrounding brain tissue on the development of commissural connections.Read moreRead less

This project seeks to identify the influence of preceding developmental stages on the correct formation of the brain. Development is a sequence of transformations where every stage depends on the outcome of previous stages. The project intends to examine how the early sensory periphery, early-born brain circuits, and intrinsic neuronal interactions affect the subsequent organisation of the cerebral cortex – a mammal-specific brain region responsible for perception, motor planning and cognition. It expects to provide novel mechanistic and conceptual insights into the process of normal brain development and more general biological phenomena, such as development and evolution. It may also provide insights into several genetic and non-genetic causes of brain malformations.Read moreRead less
