Michel A Lemay, PhD is a Professor in the Department of Bioengineering at Temple University. His research group focuses on understanding the functioning and contribution of the spinal circuitry to the control of locomotion, and how this circuitry can be re-engaged for rehabilitation purposes following injury. Dr.Lemay's group uses a number of tools to activate and probe the spinal circuitry, techniques ranging from cellular delivery of neurotrophic factors to electrical stimulation of the spinal cord or its afferent feedback to locomotor re-training and multiunit recording of interneuronal activity during locomotion. Prior to coming to Temple University, Dr. Lemay was a Professor in the Department of Neurobiology and Anatomy at Drexel University College of Medicine, and a Principal Investigator in the Spinal Cord Research Center at this institution. Dr. Lemay received his PhD and MS in Biomedical Engineering from Case Western Reserve University, and trained as a post-doctoral fellow under Drs. Neville Hogan and Emilio Bizzi at the Massachusetts Institute of Technology.
