How do interactions between axon guidance molecules bring about directed axon growth? This project deals with a fundamental, yet poorly understood biological problem at the cutting edge of international science - how axons navigate to their targets. A better understanding of this basic biological process will greatly assist the development of therapies to treat a wide range of clinical conditions in which axonal connections between neurons are disrupted by trauma or disease.

Alzheimer's disease (AD) is the most common form of dementia in the ageing population. This research project aims to identify and characterise new genes involved in the copper regulation of the Alzheimer's disease gene. This may lead to the development of novel therapeutic targets and clinical intervention strategies as well as early diagnostic procedures in preventative healthcare for the treatment of AD. The benefits would affect the international community as a whole, potentially minimising the socio-economic costs arising from the predicted world-wide increase in AD in the ageing population.Read moreRead less

Imaging genetics in schizophrenia and bipolar disorder: shared neurocognitive endophenotypes. Combined, schizophrenia and bipolar disorder afflict approximately 506,000 Australians at any one time, and are leading causes of disability and national economic burden. This study will delineate genetic underpinnings for these conditions in association with specific neurocognitive dysfunctions that are common to both disorders. These findings have important implications for the implementation of perso ....Imaging genetics in schizophrenia and bipolar disorder: shared neurocognitive endophenotypes. Combined, schizophrenia and bipolar disorder afflict approximately 506,000 Australians at any one time, and are leading causes of disability and national economic burden. This study will delineate genetic underpinnings for these conditions in association with specific neurocognitive dysfunctions that are common to both disorders. These findings have important implications for the implementation of personalised pharmaceutical treatments on the basis of genotype, and the development of therapeutic agents to target cognitive function. These results will also aid detection of premorbid psychotic illness in young individuals who may benefit from early intervention that may thwart the illness trajectory. Read moreRead less

This project will strengthen Australia's research capabilities in the areas of molecular neurobiology and neurogenetics. The project will equip students with the intellectual and technical skills needed to work in priority areas such as genomics and biotechnology, as well as in medical and agricultural research, and education. The research has possible long term applications in modifying the behaviour of insects of agricultural or medical importance. For example, by inhibiting the ability of insects to perceive specific odours it may ultimately be possible to prevent insects that carry disease from identifying target animals, or plant pests from locating their host plants.Read moreRead less
Olfactory signalling and coding in Drosophila and other insects. Animals rely on olfactory cues to detect food, danger, and others of the same species. The olfactory systems of Drosophila and other insects are simpler than those of mammals, yet complex enough to offer fascinating systems for studying neural information processing. This project aims to investigate the role of the Drosophila odorant receptors in olfactory coding, and to use multiple approaches to isolate components of the poorly u ....Olfactory signalling and coding in Drosophila and other insects. Animals rely on olfactory cues to detect food, danger, and others of the same species. The olfactory systems of Drosophila and other insects are simpler than those of mammals, yet complex enough to offer fascinating systems for studying neural information processing. This project aims to investigate the role of the Drosophila odorant receptors in olfactory coding, and to use multiple approaches to isolate components of the poorly understood insect olfactory signal transduction pathway. In addition, the role of the NO/cGMP pathway in olfactory signalling will be studied using an olfactory mutant that has nitric oxide synthase defects.Read moreRead less

The project will do this by i) discovering genes associated with speech disorder and ii) defining the neural pathways associated with speech production. This study will address critical questions regarding gene, brain and behaviour relationships in speech.
Truncating presenilin mutations and their effects on gamma-secretase activity, tau and beta-catenin - insights into Alzheimers disease and cancer. Cancer and dementia are primarily afflictions of the aged and are increasingly important in an aging Australian population. 95% of all Alzheimer's disease is spontaneous (not inherited) but we know little about the molecular mechanisms underlying it.

Cancer and dementia are primarily afflictions of the aged and are increasingly important in an aging Australian population. 95% of all Alzheimer's disease is spontaneous (not inherited) but we know little about the molecular mechanisms underlying it. Our discovery that truncated presenilin proteins potently inhibit normal protein function suggests that changes in presenilin function in aged cells might be a common molecular link between spontaneous and inherited Alzheimer's disease and could contribute to frontotemporal dementia and cancer. Our research will show whether this phenomenon might provide a breakthrough in our understanding of these diseases and be a productive area for research into their amelioration and/or prevention.Read moreRead less
