Although Dr. Samuel David is best known as a pioneer in regeneration, he is best described as a Renaissance Man. From the moment he stepped foot in Canada in 1969, he has aimed to redefine the concept of neurological injury and give us hope we can one day repair it.
Dr. David currently sits as a Professor in Neurology & Neurosurgery as well as the Department of Anatomy & Cell Biology at McGill University. He has published over 120 publications in peer-reviewed journals, reviews, and chapters in books.
Dr. David’s work focuses on three areas ranging from spinal cord and peripheral nerve injury to Multiple Sclerosis and neurodegenerative diseases. In all three cases, he has gained significant insight into how these conditions arise. More importantly, he has identified possible ways to treat some of these troubles. His work has been honoured as he has received the coveted Barbara Turnbull Award for Spinal Cord Research.
Dr. David is continuing his pioneering ways by merging the branches of neuroscience and immunology in nerve injury. His most recent achievements reveal the importance of both systems in nerve damage and highlight a role for iron in worsening these conditions.
Before pursuing a PhD at the University of Manitoba, Dr. David worked in physiotherapy first in India and then in Ontario. Upon completion of his doctorate, Dr. David did postdoctoral training at McGill University, and University College London (UK). He returned to McGill where he continued his research.
