Faculty Focus - Michael Tymianski


Michael Tymianski, MD, PhD, FRCSCTymianski-sm

Having graduated from the University of Toronto Faculty of Medicine in 1987, Dr. Tymianski undertook a comprehensive surgical internship at the Toronto Western Hospital that year before entering the Neurosurgery Training Program at The University of Toronto in 1988. During his residency, he entered the Graduate School of the Institute of Medical Science and worked towards his Ph.D. which he received in 1994. Dr. Tymianski became a Fellow of the Royal College of Physicians and Surgeons of Canada in 1995. He completed clinical fellowship training in cerebrovascular surgery with Dr. Christopher Wallace at Toronto Western Hospital in 1995 and with Dr. Robert Spetzler at the Barrow Neurological Institute in 1996. Dr. Tymianski joined the Neurosurgical Staff at the Toronto Western Hospital in 1997. He is currently a Professor in the Department of Surgery, Head of the Division of Neurosurgery at Toronto Western Hospital, and Director of the Neuroprotection Laboratory at Toronto Western Research Institute. He also holds a Tier 1 Canada Research Chair in Translational Stroke Research. Dr. Tymianski’s main clinical interest is in vascular neurosurgery. His main research interest is in the molecular mechanisms underlying stroke and emphasis in cerebral protection.  He is married to Dawn and has four children.
