Current research: 

My research program continues to be inspired and anchored in the daily clinical reality of children and adolescents who sustain mild traumatic brain injuries, as well as other traumatic injuries, and receive services from pediatric tertiary care hospitals and trauma centers. As has been the focus since the inception of my research program, the overarching aim of my work remains to better understand the consequences of mild traumatic brain injuries sustained by children and adolescents as they relate to the practice of physical activities, and to optimize recovery post-injury, by way of specific interventions, in order to facilitate and contribute to a safer and more satisfying return to physical activities. My research program therefore comprises two main research areas focusing on mTBI in children and adolescents: Theme 1 Improving the evaluation of the consequences of mTBI in the pediatric and adolescent population and Theme 2 Rehabilitation interventions following a mTBI. 

Research Areas: 
physical activity
traumatic brain injury
visual perception


I am a Professor in the School of Physical and Occupational Therapy, and Associate Member in the Division of Pediatric Emergency Medicine in the Department of Pediatrics, where I am Associate Director of Research, as well as a researcher in the Child Health and Human Development Program at the Research Institute of the McGill University Health Center. My research lab is located at the Montreal Children’s Hospital of the McGill University Health Center and is integrated within the Institutions’ Pediatric Trauma Center and Concussion Clinic. I also continue to practice on a very part-time basis in the same institution as a neuropediatric physiotherapist. The intersection between these roles greatly contributes to my integrated approach to research, teaching and service so that each element builds and informs the other.

Professional activities: 

Clinical Practice:

I am a physiotherapist at the Montreal Children’s Hospital of the McGill University Health Center. I practice as a clinician on a part-time basis and am involved in the assessment and treatment of infants and children with developmental disabilities, congenital torticollis and am also involved in the Trauma Programs specifically with children who sustain concussions/mild traumatic brain injuries.
