Patients with schizophrenia differ widely in their symptoms, long-term outcome and response to medication. However, most patients are treated with the same medications and interventions. This study aims to better facilitate the targeting of novel treatments to groups of patients (biotypes) that are likely to benefit most from a treatment. Groups of patients that share distinct patterns of deficits in brain connectivity will be delineated using state-of-the-art white matter imaging techniques.

My university position is a research chair with the specific aim of leading a team of researchers in neuropsychiatric research. One of the goals of the Centre is to deliver world-class neuroimaging research in psychiatric disorders. I head a team of researchers that have been undertaking neuroimaging and neuropsychological work on schizophrenia and psychosis since 1993 in Australia. My particular interest and impact on the field has been to define and understand progressive brain changes in schizophrenia and related psychotic disorders. Further work will place these changes within a brain maturational context, particularly examining trajectories of development in adolescence and young adulthood.Read moreRead less
Resilient Brain Networks In Patients With Schizophrenia And Their Unaffected Siblings

Funding Amount
$474,226.00
Summary
An individual’s risk for schizophrenia is usually evaluated in terms of their familial, environmental and neurobiological risk factors. Our research indicates that factors conferring resilience to becoming ill are just as important. This study will use brain imaging techniques to study individuals with schizophrenia and their unaffected siblings, aiming to identify factors that have provided the unaffected siblings with resilience to becoming ill, despite their familial risk.
Identifying Neuroanatomical Sub-phenotypes Of Schizophrenia

Funding Amount
$60,129.00
Summary
The clinical presentation of schizophrenia is varied across individuals, and has arguably hindered efforts to determine its cause/s. This project seeks to address this issue by investigating biological commonality in patients, to identify subgroups of schizophrenia patients with similar brain abnormalities, with the overall aim to examine cognitive and clinical characteristics and candidate genetic markers in association with biologically derived subtypes of schizophrenia.
Investigating The Interaction Between BDNF And Sex Steroid Hormones During Adolescent Development: Relevance To Schizophrenia
Funder
National Health and Medical Research Council
Funding Amount
$449,048.00
Summary
Schizophrenia first appears clinically during late adolescence. Sex hormones as well as growth factors such as Brain derived neurotrophic factor (BDNF) are involved in shaping the adolescent brain to its adult form. Alterations to these systems may contribute to structural changes seen in schizophrenia. This project will investigate the interaction of BDNF and sex hormones in the development of the adolescent mouse brain, and behavioural responses with relevance to schizophrenia.
The Role Of Dendritic MRNA Decay In Synaptic Plasticity & Cognition

Funding Amount

Summary
Schizophrenia is characterized by abnormal contacts between brain cells, known as synapses. Maintenance of synapses requires the translation of gene products, termed mRNA, into protein. Schizophrenia has been associated with genes involved in the degradation of mRNA, which buffers translation and thus protein levels. My research therefore seeks to study the role of mRNA decay in synaptic structure, synaptic function and cognition.
Mental illness is the largest single cause of disability in Australia. While mental illness is increasingly recognised as a disorder of the brain, a patient’s diagnosis, treatment and prediction of course of outcome is seldom guided by the results of a biological test. My research aims to combine the power of modern brain imaging and cutting-edge bioinformatics to enable a biological approach to the problem of mental illness.

Summary
Schizophrenia first appears clinically during late adolescence. This project seeks to understand the molecular changes that occur during adolescent brain development that may underlie the behavioural abnormalities found in schizophrenia. We will focus on Brain derived neurotrophic factor (BDNF), a gene which when reduced is associated with schizophrenia.

This project seeks to understand the molecular changes that occur during adolescent brain development that may underlie the behavioural abnormalities found in schizophrenia. We will focus on Brain derived neurotrophic factor (BDNF), a gene which when reduced is associated with schizophrenia. By examining the role of this gene during adolescent brain development, we will better understand how disruptions to this gene may lead to schizophrenia-like behaviours in adulthood.Read moreRead less
