Research Activities

Jiwon Oh is a staff neurologist, scientist, and Medical Director of the Barlo Multiple Sclerosis (MS) Program at St. Michael’s Hospital, University of Toronto. Dr. Oh’s research focuses on developing advanced MRI techniques in the spinal cord and brain for use in clinical settings. She leads the MRI research program at St. Michael’s Hospital, and is the principal investigator on numerous local and multi-center collaborative studies, including the Canadian Prospective Cohort Study to Understand Progression in MS (CanProCo), which is a national prospective cohort study designed to better understand progression in MS.
