Dr. Wanigatunga's primary focus is to investigate the intersection of the aging process and physical activity, a topic that broadly touches all aspects of health. He is currently exploring the interactions among the brain, physical activity, and mobility with aging. Dr. Wanigatunga's ultimate goal is to promote the infusion of healthy levels of physical activity back into the public's routine lifestyle in an effort to increase quality of life, prevent disease and disability, and positively shift the perspective of aging independently as a welcomed stage of life.
