O'Brien lab 2018
2018 O’Brien (epilepsy, neuropharmacology) group. L-R: Professor Terry O’Brien, Ms Emma Braine, Mr Michael x, Dr Kim Powell, Dr Pablo Casillas Espinosa, Mr Rafael Smith, Dr Idrish Ali, Mr Jack Germaine, Dr Loretta Piccenna

Research Overview

The group’s research is broad based translational, covering both basic and clinical studies investigating to epilepsy and related areas, including traumatic brain injury and dementing disorders. The work has had two primary goals:  1. better understand the determinants of treatment response by identify biomarkers for treatment outcomes – imaging, electrophysiological, genomic and clinical, and to develop new treatment approaches. 2. To investigate the fundamental neurobiological basis of the neuropsychiatric and medical co-morbidities present in many patients with epilepsy and related conditions. We have a major focus on developing new treatments, testing them in pre-clinical studies, and then translating these into early phase clinical trials. The group integrated with the Department of Neurology in the Alfred Hospital, including the dedicated Neurological Clinical Trials Facility which has capacity for first-in-disease clinical trials.
