Clinical neuroscience


Professor O’Sullivan’s holds a joint appointment as a Professor of Neuroscience at QBI and as Director of the Mater (clinical) Centre for Neuroscience. Professor O’Sullivan is an eminent neurologist with extensive clinical research experience. His lab will lead the establishment of the clinical interface between QBI clinicians, researchers, and the wider community. Professor O’Sullivan has substantial experience in the application of diffusion MRI, tractography and functional MRI to understand the interaction between focal damage and other processes involved in ageing and early cognitive decline, viewed from a network perspective.

With significant clinical experience, Professor O’Sullivan’s research focus is translational in nature, promoting the restoration of brain function. His previous work has been aimed at identifying mechanisms of resilience and restoration of function that can be targeted by therapies that promote recovery; the STRATEGIC study targets such mechanistic insights in stroke. Professor O’Sullivan has consulted in numerous UK clinics and hospitals with a focus on hyperacute stroke services, microvascular disease and genetic forms, and post-stroke cognitive impairment and dementia.
