Summary
Neurons are faced with diverse forms of stress everyday. Neural diseases exacerbate this stress, causing interference to genes that normally allow neurons to function correctly. As a result, neurons die, and severe loss can result in diseases such as dementia. We have discovered new molecular factors in neurons that insulate their genes from stress, thereby protecting neuron function and health. The proposed research will exploit these mechanisms to better protect neurons from disease.
Decoding Mechanisms Of Brain-intestinal Communication

Summary
Obesity is a worldwide concern to human health. Research into how fat is regulated in the body may provide new therapeutic options. It is not well understood how signals from the brain control fat storage. We have recently identified a gene that is important for the communication between the brain and the intestine in the control of fat levels. As such, our work will enable us to better understand this phenomenon.
Cracking The Epigenetic Code: Understanding The Mechanisms Of Memory Associated With Anxiety-related Disorders And Their Treatment

Summary
The primary goal of my research programme is to elucidate how the epigenome coordinates experience-dependent gene expression underlying associative learning and memory using paradigms relevant for understanding fear-related anxiety disorders. My research on DNA modifications and newly emerging findings in the realm of RNA biology is changing the way we think about gene-environment interactions, the broader impact of which will most certainly continue to be felt for years to come.
Controlling The Development And Function Of Hindbrain Commissures In Vertebrate Animals: The Role Of Robo3 Receptor

Summary
Commissural axons connect and coordinate activity between neurons of the left and right sides of the central nervous system. In the forebrain, formation of commissural axons is determined by guidance factors at the midline between the two hemispheres, and abnormalities in guidance can cause developmental malformations. The aims of this project are to elucidate function of the Robo/Slit family of molecules in regulating axon guidance of commissural neurons, particularly in the corpus callosum.

Summary
Tumour associated epilepsy, a common, disabling problem for patients with brain tumours called gliomas is often refractory to medical treatment and the mechanisms by which gliomas cause seizures are unknown. This is the first extensive observational study looking at molecular factors within the brain such as Hyperpolarization ion channels, glutamate uptake receptors and ADAM22 genes that may help determine which patients with gliomas will develop epilepsy and which ones will not.
Detection And Manipulation Of Neuronal Activities With A Synthetic Optogenetic Activity-reporting Transcription System

Summary
Functional brain mapping is important for understanding mental illnesses such as depression, attention deficit hyperactivity disorders and post-traumatic stress disorders. Current techniques for functional brain mapping are limited and not suitable for large-scale studies. The proposed project will generate new tools that can be used to map activated neurocircuitry in laboratory model organisms and will enhance our ability to design effective treatments for mental illnesses.

Summary
Mutations and dysregulation of the SNX27-retromer protein platform are strongly linked to Alzheimer’s disease (AD) and Parkinson’s disease (PD). This research program will determine how SNX27-retromer interacts with key molecules associated with AD and PD, the outcomes of which be significantly improved understanding of how mutations in these proteins cause disease, and a necessary molecular framework for future therapeutic targeting.

Summary
Bipolar disorder and schizophrenia are two major psychiatric conditions affecting over 800,000 Australians. We have identified a new gene which contributes to increased risk to developing both bipolar disorder and schizophrenia. We will investigate the function of this gene in normal brain development, and how this function is disrupted in individuals with bipolar disorder and schizophrenia. Understanding the biological cause will help us define better treatments for these severe mental illnesse ....Bipolar disorder and schizophrenia are two major psychiatric conditions affecting over 800,000 Australians.

Summary
Abnormal levels of cell surface receptors in neurons can lead to a variety of debilitating neurological disorders and neurodegenerative diseases. These levels are tightly regulated through the orchestrated movements of receptors from inside the neuron to the cell surface. In this project we will examine how the transport of cell surface receptors is regulated by an intracellular signalling molecule, called copine, which is important in both epilepsy and Alzheimer’s disease.
