Jean-Sebastien is a researcher at the Centre for Interdisciplinary Research in Rehabilitation and Social Integration (CIRRIS) and a Full Professor in the Rehabilitation Department at Universite Laval (Quebec City, Canada). His research interests lie in defining the central (neural) and peripheral (joint-level) factors associated with the onset and chronicization of musculoskeletal disorders, and in evaluating the effects of rehabilitation approaches to prevent or rehabilitate musculoskeletal disorders. Other interests include to better understand normal joint control, mechanisms underlying motor learning or re-learning (post injury), and factors that impact both joint control and motor learning. He has published over 120 articles in peer-reviewed journals and 7 book chapters, mainly on neuromuscular and biomechanical mechanisms of musculoskeletal disorders, and has given over 50 presentations at national and international conferences. Before being involved full time in research, he has worked for 10 years as a physical therapist at the Laval University Hospital, specializing in the treatment of musculoskeletal disorders.
