Professor Clark is a translational physiologist whose overarching research goal is to develop effective and implementable interventions that increase muscle function (e.g., muscle strength, motor control, fatigue-resistance) and physical performance in older adults or patients of any age who have orthopedic and neurologic disabilities for preventative and rehabilitation medicine.
His work has heavily focused on the integration of exercise physiology, nutrition and pharmacologic interventions, and conservative therapies to improve the quality of life for the elderly as well as those with chronic and recurrent pain conditions. He is a fellow of the American College of Sports Medicine and a standing member of the NIH's Motor Function, Speech and Rehabilitation (MFSR) Study Section.
Professor Clark has designed and carried out many integrative human physiology experiments as well as clinical trials involving healthy adults, elderly individuals, as well as those with selected musculoskeletal and neurological disorders (e.g., low back pain, post-stroke spasticity). He has published extensively in the above-mentioned areas, having written over 80 journal articles or book chapters and more than 125 abstracts.
These publications have been published in highly reputed journals such as Current Opinions in Nutrition and Metabolic Care, Exercise and Sport Science Reviews, Experimental Gerontology, Journal of Applied Physiology, Journals of Gerontology Medical Sciences, Journal of Neurophysiology, PLoS One, and Spine. He has served as Guest Editor of several topic issues of selected journals including Frontiers in Aging Neuroscience, and is a reviewer for most of the major international medicine, physiology, neuroscience, exercise, and gerontology journals
