The Research of the Epilepsy and Neuropharmacology Research Group is broad based, covering both basic and clinical studies relevant to epilepsy and related areas, including traumatic brain injury and dementing disorders.
The Group's Research has had two primary goals: First to better understand the determinants of treatment response by identify biomarkers for treatment outcomes – imaging, electrophysiological, genomic and clinical, and to develop new treatment approaches. Second to investigate the fundamental neurobiological basis of the neuropsychiatric co-morbidities present in many patients with epilepsy and related conditions.
The group has an extensive network of collaboratiors, locally, nationally and internationally. We are highly active in research training, with more than 25 PhD students compled over the past 15 years, as well as multiple Masters, Honours, and Medical Students in research. We are always welcoming of new students who are bright and enthusiastic about udertaking basic or clinical research that aims to ultimately made a difference to patients lives. Our research is funded by multiple NHMRC, ARC and international grants, as well as Philanthropic support, in particular from the RMH Neuroscience Foundation, and industry partnerships.
