Jean-Sébastien is a researcher in the Centre for Interdisciplinary Research in Rehabilitation and Social Integration (CIRRIS) and an Associate Professor in the Rehabilitation Department at Laval University (Quebec City, Canada). His research interests lie in defining the central (neural) and peripheral (joint-level) factors associated with the occurrence and chronification of musculoskeletal disorders (mainly at the shoulder joint), and in evaluating the effects of rehabilitations approaches to prevent or rehabilitate shoulder disorders. Other interests include to better understand normal shoulder motor control, mechanisms underlying motor learning or re-learning (post injury), and factors that impact both shoulder motor control and motor learning. He has published over 70 articles in peer-reviewed journals and 6 book chapters, mainly on neuromuscular and biomechanical mechanisms of shoulder 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 shoulder disorders.
