Researcher biography
After completing neurology training at the Royal Brisbane & Women's Hospital(RBWH) in 1995, A/Prof O'Sullivan completed Fellowships in Movement Disorders at the Austin & Repatriation Medical Centre, Melbourne then the National Hospital for Neurology and Neurosurgery, and Middlesex Hospital in London, UK. He was awarded a doctorate in Medicine from Melbourne University in 2000 for studies into surgery for Parkinson's disease. He returned to the RBWH in 2001 and set up the Movement Disorders Clinical Service including botulinum toxin and later Friedreich's ataxia clinics, and co-ordinating the Huntington's disease multidisciplinary clinic. Through these clinics he has established collaborations with local, interstate and international researchers in the fields of Parkinson's disease, and other movement disorders and neurodegenerative diseases. He is currently Associate Professor of Medicine and Principal Research Fellow at UQ Centre for Clinical Research, previously Royal Brisbane and Uniting Care Health Clinical Units in UQ School of Clinical Medicine. A/Prof O'Sullivan past President of the Movement Disorders Society of Australia and New Zealand (MDSANZ), having previously served as Chair of the MDSANZ Clinical Trials and Research Group. He is on the Council of the Australian and New Zealand Association of Neurolgists (ANZAN) and previously chaired the ANZAN Scientific Program Committee
