Faculty Focus - Mark Erwin
Mark Erwin, DC, PhD
Dr. Mark Erwin obtained his Doctor of Chiropractic from the Canadian Memorial Chiropractic College in 1984 and later completed his Ph.D. in Medical Sciences at the Institute of Medical Sciences, University of Toronto in 2004. Dr. Erwin was cross-appointed as an assistant professor and staff scientist for the Division of Orthopaedic Surgery and Division of Neurosurgery Spine Programme at the University of Toronto. Since this time, Dr. Erwin has been appointed an associate professor at the Canadian Memorial Chiropractic College, a Scientist at the Toronto Western Research Institute and an Affiliate Scientist for the Division of Neurosurgery, University of Toronto. Dr. Erwin’s research takes a cellular/molecular approach in order to both understand and treat degenerative disc disease and associated disorders of connective tissue. His research has been facilitated by both his expertise in his field, as well as peer-reviewed funding from sources such as the AO-Spine and the North American Spine Society and philanthropic sources. Between 2003 and 2007, Dr. Erwin received the CIHR/CCA Senior Research Award and was appointed the Chiropractic Research Chair at the University of Toronto. In addition to the positions Dr. Erwin holds at the University of Toronto and Canadian Memorial Chiropractic College, he is also a member of over ten scientific organizations – including the North American Spine Society, Canadian Chiropractic Association and AO Spine International – and he sits on the review board for nine academic journals.
