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.
Prof Alan Connelly is an internationally recognised neuroimaging researcher specialising in MRI. His major areas of research are in the development of new methods to acquire and process MR images of both structural and functional aspects of the brain, and the application of these novel methods to clinical neuroscience problems. His work has had a major impact in the field of epilepsy, where techniques that he pioneered have been widely adopted in specialist epilepsy centres worldwide.
I use multidisciplinary and neuroimaging approaches to understand how the biochemistry of the brain affects how the brain functions in health and disease. This basic science underpins treatment approaches and furthers our understanding of a wide range of brain disorders.
Mild traumatic brain injury (TBI) is a leading cause of death and disability in Australia, especially in young populations. Although many patients recover uneventfully following mild TBI, complications such as prolonged symptoms, depression and cognitive deterioration may occur. With considerable advancements in neuroimaging and cognitive assessment in recent years, newer techniques may provide a window to directly observe changes that accompany mild TBI.
Structural Connectomes In Traumatic Brain Injury: Can Secondary Disease Progression Be Stopped And Cognitive Deficits Be Reversed?

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.
Mood and anxiety disorders represent a tremendous cause of disability and morbidity. This research will use cutting-edge brain imaging technologies to understand why these disorders typically emerge in young people and whether brain imaging can reliably predict the effectiveness of different treatments for individual patients.
Identifying Neuroanatomical Sub-phenotypes Of Schizophrenia

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.
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.
EXTEND-IA Randomized Trial Of Intra-arterial Clot Retrieval In Ischemic Stroke

Funding Amount
$764,534.00
Summary
Most strokes are caused by a blocked blood vessel in the brain. Current treatments to dissolve the blockage improve recovery for many patients but often fail to unblock larger brain arteries. The EXTEND-IA trial will use advanced brain imaging to identify patients who have the most to gain if the blocked artery can be re-opened. The trial will test whether a new minimally invasive clot removal procedure performed after standard clot-dissolving treatment improves recovery after stroke.
