Michel Lemay, PhD, is an adjunct professor of neurobiology and anatomy at Drexel University College of Medicine, and a professor in the Department of Engineering at Temple University. He received his PhD in biomedical engineering from Case Western Reserve University. Following training as an NIDRR and SCRF postdoctoral fellow at MIT and as a research associate at Case Western, Dr. Lemay joined the faculty at Drexel University College of Medicine/MCP Hahnemann University in 2001 and moved to Temple in 2013.


Dr. Lemay's research focuses on studies and applications of the neuronal circuitry for restoring movement after spinal cord injury. His laboratory is interested in studying and utilizing spinal circuits responsible for movements in neural prosthesis applications. Neural prostheses use electrical activation of a damaged nervous system to restore function to the affected individual. Dr. Giszter's laboratory demonstrated the modularity of the spinal frog motor output to intraspinal microstimulation, while my laboratory and a number of other groups have shown similar modules for movement control in the mammalian spinal cord.

The laboratory is currently focusing on elucidating the effects of spinal injury on the spinal motor output and neuronal circuitry, and the interactions between intraspinal microstimulation, neural transplants promoting regeneration and sensorimotor training aimed at shaping the regenerating pathways.

The tools and techniques used include computer-based modeling of limb biomechanics, multiunit neuronal recordings, kinematic analysis of movement behavior and in vivo stimulation and recording of force, motion and muscular activation in preclinical models.
