Psychiatric disorders in epilepsy. Psychiatric disorders, such as depression, anxiety and cognitive disorders, are frequently observed in patients with epilepsy. Although standard dogma suggests that psychiatric disorders are a consequence of living with epilepsy, recent evidence suggests a bidirectional relationship between these disorders, such that depression and other psychiatric illnesses act as risk factors for epilepsy development. This project will utilise basic science approaches to und ....Psychiatric disorders in epilepsy. Psychiatric disorders, such as depression, anxiety and cognitive disorders, are frequently observed in patients with epilepsy. Although standard dogma suggests that psychiatric disorders are a consequence of living with epilepsy, recent evidence suggests a bidirectional relationship between these disorders, such that depression and other psychiatric illnesses act as risk factors for epilepsy development. This project will utilise basic science approaches to understand the causal relationships between epilepsy and psychiatric disorders, and determine how and why psychiatric disorders and epilepsy co-exist. It is hoped that research conducted in this project will develop novel avenues to treatment of both epilepsy and psychiatric disorders.Read moreRead less
UNDERSTANDING THE BASIS OF COMPLEX BEHAVIOUR. This project is anchored in the fundamental understanding of complex vertebrate behaviours, namely cognition. Little is known about the molecular and neural substrates underpinning complex higher order information processing. This project aims to dissect the functional role of synaptic genes that are essential for organising neuronal connections, in distinct cognitive processes and how these functions may be regulated by other genes, drugs or environ ....UNDERSTANDING THE BASIS OF COMPLEX BEHAVIOUR. This project is anchored in the fundamental understanding of complex vertebrate behaviours, namely cognition. Little is known about the molecular and neural substrates underpinning complex higher order information processing. This project aims to dissect the functional role of synaptic genes that are essential for organising neuronal connections, in distinct cognitive processes and how these functions may be regulated by other genes, drugs or environmental factors. This project aims to employ state-of-the-art technologies to address the evolutionary biology of complex cognitive behaviours, towards further understandings how brain function evolved and the mechanisms that have enabled humans to perform highly complex and intricate tasks.Read moreRead less
I am a neuroscientist employing strategies of anatomy, biochemistry, pharmacology, genetics and behavioural analysis to examine the physiological and possible pathological roles of newly discovered neuropeptides and their cognate receptors in mammalian brain. My recent research has focused on the highly-conserved, abundant peptide, relaxin-3 that was discovered at the HFI in 2002. Studies so far have revealed that relaxin-3 is a powerful modulator of rhythmic brain activity (theta) and spatial m ....I am a neuroscientist employing strategies of anatomy, biochemistry, pharmacology, genetics and behavioural analysis to examine the physiological and possible pathological roles of newly discovered neuropeptides and their cognate receptors in mammalian brain. My recent research has focused on the highly-conserved, abundant peptide, relaxin-3 that was discovered at the HFI in 2002. Studies so far have revealed that relaxin-3 is a powerful modulator of rhythmic brain activity (theta) and spatial memory, and alters feeding, body weight and arousal. Relaxin-3 levels in brain are also strongly activated by acute stress. In the future, I aim to elucidate further the role of relaxin-3 systems in normal physiology and metabolic and-or psychiatric diseases.Read moreRead less
The role of synapse development in cognitive disorder. In humans, intellectual disability occurs when nerve cells in the brain fail to connect. The project examines fundamental molecular processes involved in synapse development of neurons. The use of insect models provides a generalised biological template to understand how synaptic molecules contribute to behaviours that underlie cognitive disorder.
Central pathways regulating visceral pain. This project aims to investigate the neural pathways within the spinal cord and brain processing colorectal pain perception. The project aims to identify the spinal cord neurons relaying colorectal signalling into the brain and the influence of descending modulation from the brainstem upon these pathways. The outcomes will greatly benefit fundamental understanding of the central pathways processing visceral pain.

Summary
The regulation by transcription factor phosphorylation upon the myelinating process. The project will investigate the novel molecular events that control the myelinating process, which is essential for normal nervous system function. Outcomes of this project may aid the development of novel interventions to improve control of demyelinating diseases, which represent a substantial socio-economic burden.
The development and testing of a device to enhance the application of repetitive transcranial magnetic stimulation. This project aims to develop and evaluate a new device designed to substantially enhance the use of transcranial magnetic stimulation, a technology, which is increasingly being applied in the treatment of disorders such as depression, as well as in the study of normal and abnormal brain function.
How the brain regulates blood pressure. This project will test whether a group of nerve cells in the rostral ventrolateral medulla generate sympathetic activity in blood vessels. The brain regulates blood pressure through several pathways, including nerves in the sympathetic nervous system that constrict blood vessels and increase the heart rate. Activity of these sympathetic nerves regulates blood pressure, but it is unknown which nerve cells in the brain cause this activity. This information i ....How the brain regulates blood pressure.

The brain regulates blood pressure through several pathways, including nerves in the sympathetic nervous system that constrict blood vessels and increase the heart rate. Activity of these sympathetic nerves regulates blood pressure, but it is unknown which nerve cells in the brain cause this activity. This information is essential to understand how blood pressure is controlled under healthy conditions.Read moreRead less
Use of an animal model to understand mechanisms underlying reductions in body weight associated with use of the laparoscopic adjustable gastric band. At least one in ten Australians is classified as morbidly obese and as such are eligible for bariatric surgery. Those undergoing the surgery will achieve an average excess weight loss of up to 60 per cent, they will have reduced or eliminated diabetes and will appreciably improve their prospects of survival. These experiments aimed at understandin ....Use of an animal model to understand mechanisms underlying reductions in body weight associated with use of the laparoscopic adjustable gastric band. At least one in ten Australians is classified as morbidly obese and as such are eligible for bariatric surgery. Those undergoing the surgery will achieve an average excess weight loss of up to 60 per cent, they will have reduced or eliminated diabetes and will appreciably improve their prospects of survival. These experiments aimed at understanding the mechanisms underpinning this success have the potential to further improve surgical approaches and outcomes and provide insights that will better enable weight loss therapies for all overweight and obese Australians.Read moreRead less
Gene-environment interactions mediating experience-dependent plasticity in the healthy and diseased brain. The aim of this project is to understand how genes and environment combine to affect susceptibility to various brain disorders, using models of human diseases and manipulating environmental factors such as mental and physical activity. The project's focus is on neurological and psychiatric disorders, including Huntington's disease, depression, schizophrenia and autism.
