Dr. Bar-Or, a neurologist and neuroimmunologist, was Professor in the Department of Neurology and Neurosurgery, and Associate Director (Clinical and Translational Research) of the Montreal Neurological Institute and Hospital, McGill University, prior to taking on position of Presidential Endowed Chair at the University of Pennsylvania (UPenn/CHOP) where is founder and Director of the Centre for Neuroinflammation and Experimental Neurotherapeutics. His clinical focus is Multiple Sclerosis (MS) and related disorders in both adults and children, and he runs a cellular and molecular Neuroimmunology lab that studies basic principles of immune regulation and immune-neural interaction, in the context of inflammation, injury and repair of the human central nervous system (CNS). Research themes are directed at understanding principles of immune-regulation, elucidation of effector and regulatory mechanisms of distinct immune cell (principally T cell, B cell, and myelid cell) subsets in CNS inflammatory disease; immune reconstitution, neuroimmune interactions and mode of action of emerging therapies. He is past President of the Canadian Network of MS Clinics (CNMSC) and past member of the Board of Directors of the Federation of Clinical Immunology Societies (FOCIS) where he continues as a member of the Education Committee. He also serves on the Board of Directors of the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) and on the Steering Committee of the Immune Tolerance Network (ITN). Dr. Bar-Or is the VP/President elect of ISNI.
