Summary
Diabetic retinopathy is one of the most feared complications of diabetes. This project will examine the role that retinal immune cells called microglia have in causing early changes in the vasculature. We will examine whether diabetes changes the way neurons communicate with blood vessels, opening up a possible treatment target that could prevent the progression to more advanced disease.

Summary
Over recent years our team has developed a retinal implant to restore sight to people with certain types of blindness. With 256 independently controllable electrodes this device is among the most sophisticated in the world. We aim to conduct experiments to demonstrate that our device can provide improved better visual acuity than the world leaders with a view to developing a competitive commercial medical technology.
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 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.
Novel Retinal Architectural Vascular Signs And Risk Of Cardiovascular Disease: The AusDiab Study

Summary
Cardiovascular disease (CVD) and diabetes are major health problems. Identifying 'people at risk' is critical to design preventative strategies. We have developed new computer software to measure detailed characteristics of retinal vessels. By appling this system to predict CVD or diabetes in the AusDiab Study we aim to find 'the best combination of risk factors' to predict CVD and diabetes. This will open up the possibility of new risk assessment using a simple 'eye scan.'

Glial Plasticity: How experience and aging change brain structure. 50 % of the cells in the brain are called glia. These cells work with neurons to regulate how we think, feel and behave. Most glial cells are added to the brain after birth, however we know very little about how this process works, or how it may be changed by lived-experience. The overarching aim of this study is to better understand how lived-experience impacts the growth of the major types of glial cells in the brain.

These cells work with neurons to regulate how we think, feel and behave. Most glial cells are added to the brain after birth, however we know very little about how this process works, or how it may be changed by lived-experience. The overarching aim of this study is to better understand how lived-experience impacts the growth of the major types of glial cells in the brain. To do this, I will use cutting-edge technologies and identify; 1) the rates of cell growth for the major types of glia, and 2) map how they are integrated into the brain. This will lead to important new information on how lived-experience can shape the growth and structure of the brain.Read moreRead less
A novel sensory neural circuit has been identified innervating the airways and lungs. The anatomical organisation of this circuit has been described to some extent in previous studies, however there is a significant gap in knowledge with respect to its functional importance. This project will develop methods to address this knowledge gap and in doing so the project will firstly describe how this circuit controls breathing under normal conditions and secondly how this becomes dysregulated during

Expected outcomes of this project include constructing detailed maps of the brain circuits for fluid and salt intake by tracing multiple nodes in the network, characterising neuronal populations, and precisely defining their functions. This should provide significant benefits including understanding the brain regions controlling fluid and salt intake which are essential for maintaining fluid homeostasis, and providing a framework for investigating the neural circuits underlying other complex behaviours.Read moreRead less
