Dr. Sridar Narayanan obtained his PhD in Neurological Sciences at McGill University under the mentorship of Prof. Douglas Arnold. His thesis work employed multimodal MR imaging and spectroscopy techniques to help define the importance of axonal injury in multiple sclerosis (MS), and to characterize the evolution of axonal injury over the course of the disease. He currently is an Assistant Professor in the Department of Neurology and Neurosurgery at McGill University, and is a scientist at the McConnell Brain Imaging Centre of the Montreal Neurological Institute. His overall research interest is to study mechanisms of injury, repair and progression in neurological diseases, particularly MS, through the development and in vivo application of advanced brain image acquisition and analysis techniques. Current projects include: development and validation of methods to detect subpial cortical demyelinating lesions in living MS patients using surface-based analysis of structural MRI and myelin-sensitive magnetization transfer imaging (MTI); development of in vivo markers of demyelination and remyelination; assessing the importance of cerebral oxidative stress in MS; studying acquired demyelination syndromes and MS in children. Dr. Narayanan also has extensive experience developing and supervising the implementation and deployment of MRI protocols in multicenter clinical studies of MS and other neurological conditions.
