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.
Enzymes that generate or degrade peptides serve important roles - alterations in their activity can impact on a diverse range of physiological processes in healthy and diseased states. Angiotensin is a peptide that plays a critical role in regulating blood pressure and fluid balance - drugs that block the activity of its processing enzymes forms an important class of medication used to treat hypertension and heart disease. My research interest is in discovering novel roles for these enzymes.
Neurobiological ‘risk’ And ‘resilience’ Biomarkers Of Severe Mental Illness

Summary
Mental disorders of childhood (schizotypal disorder, autism spectrum disorders) and adolescence (psychoses, schizophrenia) represent a major burden of disease. We will use sophisticated neuroimaging to examine trajectories of brain growth from childhood to adulthood and identify factors (stress, drugs, inflammation, genes) relevant to risk and resilience to developing these disorders. This will lead to novel early interventions to reduce or ameliorate these conditions.
Outcome Prediction, Stratification And Novel Treatments In Individuals At Ultra High Risk Of Psychosis

Summary
The Ultra High Risk (UHR) criteria have been developed to identify people at high risk of psychotic disorders such as schizophrenia so that treatments can be provided early to reduce risk and disability. However the some UHR people are at risk of other difficulties and disorders and others are not at risk of all. We need to improve our ability to distinguish between these groups so that treatment can be tailored according to risk, and develop new treatments that target underlying problems.
Through this Australia Fellowship, Prof Keall and his tream will substantially improve the accuracy and effectiveness of radiation therapy for cancer by developing new techniques that will be able to ‘target’ a tumour in real-time and ‘concentrate fire’ on the most resistant and aggressive parts of it. Success in physiological targeting will create a paradigm shift in radiation therapy and could literally be a lifesaver.

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.
Maps, Models And Modifiers Of Brain Changes In Psychosis

Summary
Psychosis fundamentally alters one’s relationship with reality. Brain scans can map which parts of the brain are affected by psychosis, but they cannot identify the cellular processes that cause these changes. My fellowship aims to address this gap by integrating brain imaging with genetics and mathematical modelling to identify the brain circuits and molecules that impact risk for psychosis, and to develop targeted therapies to modify these dysfunctional circuits.
Gene-environment Interactions, Experience-dependent Plasticity And Pathogenic Mechanisms In Mouse Models Of Cognitive And Affective Disorders. Mental And Physical Activity As Modulators Of Brain And Behaviour In Healthy And Diseased States.

Funding Amount

Summary
Our aim is to understand how genes and environment combine to affect susceptibility to various brain disorders. We are using specific models involving human gene mutations associated with diseases, and manipulating environmental factors such as mental and physical activity. We are focused on neurological and psychiatric disorders, including Huntington’s disease, depression and schizophrenia. These efforts to understand brain diseases will facilitate development of therapeutic approaches.

Summary
My vision for the next 5 years is to establish ?-3PUFAs as a first-line treatment for indicated prevention of psychosis and persistent depression, as an alternative to conventional antidepressants for the treatment of moderate-to-severe depressive symptoms in adolescents and to build capacity in this area by training the next generation of researchers.
Neurodevelopmental Mechanisms And Early Intervention In Psychiatric Illness

Summary
Schizophrenia and depression are devastating mental illnesses and a huge burden to society. Drug treatments can be beneficial, but many patients are either treatment-resistant or show severe side-effects. There is an urgent need for truly novel treatment strategies which should ideally prevent symptoms. The main aim of this project is to elucidate brain mechanisms involved in schizophrenia and depression development to inform clinical research about improved preventative treatment strategies.
