Biography

My research goal is to enhance evidence-based practice in physical therapy rehabilitation practice and to aid in development of a scientific framework to design efficient rehabilitation strategies for walking and balance improvement. My research interests include understanding the neural control of movement, assessment of asymmetrical walking post-stroke, assessment of impaired walking using biomechanical, neurophysiologic and clinical measures and designing therapeutic strategies to improve walking and balance function. Furthermore, I am interested in evaluating the risk for falls in different neurological and geriatric populations and designing efficient and effective assessments to evaluate balance and mobility. I utilize the International classification of Functioning as a framework for my research interests. I believe that quantification of walking impairments and understanding their relation to functional walking performance are pivotal to develop targeted therapeutic strategies to improve functional walking ability.
