Mapping And Restoring Brain Networks Underpinning Psychiatric Symptoms

Funding Amount
$645,205.00
Summary
My research investigates how networks of brain regions dynamically communicate to support human behavior. I am interested in how brain network activity deviates from the norm to give rise to psychiatric symptoms. Results from my work will facilitate targeted research and interventions aimed at treating symptoms of psychiatric disorders.
Psychiatric disorders are associated with considerable social and economic burden which could be reduced if we understood mental health outcomes in high risk populations. This fellowship will use advanced brain imaging to understand the development of mental health disorders in those at high risk of bipolar disorder and dementia.
Structural Connectomes In Traumatic Brain Injury: Can Secondary Disease Progression Be Stopped And Cognitive Deficits Be Reversed?

Funding Amount
$431,000.00
Summary
Many people with traumatic brain injury (TBI) experience cognitive problems, including poor memory and concentration. TBI is often referred to as a ‘hidden disability’ because the overwhelming majority of patients with TBI show no abnormalities on standard MRI or CT scans. In my project, I will delineate the mechanisms of secondary injury in finer detail through enhanced neuroimaging techniques, resulting in new assessment and treatment modalities for individuals with TBI.
Promoting Plasticity And Functional Recovery In The Adult Brain: Enrichment And Transcranial Magnetic Stimulation
Funder

Funding Amount
$402,493.00
Summary
The adult human brain is unable to repair itself: axons do not regenerate effectively and there is limited reorganisation of remaining projections. Our research directly addresses how to form anatomically accurate and thus functionally useful networks through improving axonal regeneration per se, but more importantly it investigates clinically relevant, non-invasive methods that encourage the remaining nerve cells to reorganise, maximising the surviving resources of the damaged brain.
Novel Methods To Study Structural-functional Connectivity In Epilepsy And Schizophrenia

Funding Amount
$697,605.00
Summary
Magnetic Resonance Imaging (MRI) is a non-invasive method that has revolutionised our understanding of clinical neuroscience. MRI provides not only high-contrast anatomical images, but also information on brain physiology and function. My primary goal is to develop and optimise novel MRI methods for a more accurate measure of brain structure and function. My research program will focus on the application of these methods to the investigation of epilepsy and schizophrenia.
Combined TMS-EEG For Early Diagnosis Of Alzheimer’s Disease

Funding Amount
$603,767.00
Summary
Early diagnosis of Alzheimer's disease is key to more effective early intervention. Current biomarkers are expensive and are not suited for detecting the subtle changes in brain function that occur during the initial stages of the disease. Non-invasive brain stimulation is pain-free and inexpensive, and can directly probe brain function in conscious humans. This project will investigate whether these techniques might be used to identify markers of early brain dysfunction in Alzheimer’s disease.
Investigating The ‘Silent Epidemic’ Of Mild Traumatic Brain Injury: A TMS-EEG Study

National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
Mild traumatic brain injury (mTBI) is common following an impact to the head. These injuries can affect brain function for many years after the initial incident, are associated with the development of serious conditions such as depression or Alzheimer’s disease, and increase the risk of suicide. This project will use cutting edge neurophysiological techniques to better understand how mTBI affects the brain, and to identify new strategies for restoring brain function following injury.
Selective Modulation Of Neural Network Activity Using Focal Brain Stimulation

Funding Amount
$531,496.00
Summary
Transcranial magnetic stimulation (TMS) has been touted as a viable treatment for a range of psychiatric and neurological disorders. However, the extent to which localised TMS influences widespread brain networks remains unknown. To fill this gap, we will combine neuroimaging and TMS in healthy adults. The project will provide a scientific foundation for the use of brain stimulation as an effective tool for improving function in a range of clinical conditions.
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.
