Bio Sketch

Dr. Steven is currently a Professor and the Richard and Beryl Ivey Chair of the Department of Clinical Neurological Sciences.

Dr. Steven joined the Department in 2003 and has devoted his career to the surgical treatment of epilepsy. He is the surgical co-director of the epilepsy program at LHSC and has helped build it into the largest program in Canada. 

Dr. Steven is very dedicated to residency and fellowship education. He served as the residency program director and continues to direct the epilepsy surgery fellowship at Western. The epilepsy surgery fellowship has become the premiere fellowship of its kind in Canada with fellows from all over the world being trained in London. 

Nationally, Dr. Steven has been heavily involved with the Royal College of Physicians and Surgeons of Canada as a member of the Specialty Committee in Neurosurgery, a Royal College surveyor and examiner. He has been an examiner since 2008 and is the current Chair of the Royal College Examination Board in Neurosurgery. Internationally, Dr. Steven represents Canadian Neurosurgical Society on the Neurosurgery Advisory Board of the American College of Surgeons. He has also devoted considerable time developing epilepsy surgery in Peru and helping develop post-graduate medical training in neurosurgery and neurology in the Middle East.


Dr. Steven has on-going research in clinical outcomes of epilepsy surgery.
