      Dr. Salem is an Associate Professor in the Department of Biokinesiology and Physical Therapy and Co-Director of the Musculoskeletal Biomechanics Research Laboratory (MBRL). Within MBRL, he directs the Exercise and Aging Biomechanics research program. This program recognizes the growing importance of exercise and activity interventions in improving health and life-quality across the lifespan. Investigations are designed to: 1) quantify the musculoskeletal loading and neuromuscular recruitment patterns associated with functional activities and exercise; 2) examine the influence of exercise prescription on muscle dynamics, tissue adaptation, neural control, and physical performance; and 3) examine the feasibility, efficacy, and mechanisms-of-action associated with the integration of complementary and alternative modalities (CAM) (e.g. yoga, meditation, guided imagery) with traditional rehabilitation therapy. Study participants include children, younger & older adults, elite athletes, and patients with neurological disease.
