Dr. Keyser received his PhD in exercise physiology and experimental medicine from the University of Toledo and post-doctoral experience in cardiovascular disease at Harper Hospital, Wayne State University School of Medicine.  He subsequently served as Chief of Cardiovascular Physiology and Rehabilitation at Butterworth Hospital where he investigated the influence of active muscle mass on cardiac regulation during maximum and sub maximal exercise in patients with cardiovascular disease.  He held faculty research and teaching positions at both Michigan State and Grand Valley State Universities at that time.  Dr. Keyser then led the development and implementation of the PhD in Physical Rehabilitation Science Program ate the University of Maryland School of Medicine, where he served as its Director.  He also served as the Department of Physical Therapy and Rehabilitation Science, Director of Research and as the Director of the Medical School’s Exercise and Applied Physiology Core Laboratory in its NIH funded General Clinical Research Center.  While at Maryland, Dr. Keyser began to hypothesize that impaired muscle oxygenation is one mechanism for excessive fatigue and established this hypothesis in individuals who have systemic lupus erythematosus and HIV; albeit the specific mechanisms seem to differ between these groups.  In addition to investigating this hypothesis, Dr. Keyser is also the Lead Associate Investigator and site Principal Investigator on a project funded intramurally by the NIH and in collaboration with INOVA Healthcare investigating mechanisms of impairment and exercise induced improvement in patients who have pulmonary hypertension.  Dr. Keyser is a Fellow of the American College of Sports Medicine, an Associate Editor for Medicine and Science and Sports and Exercise, and a Clinical Scientist in the Department of Rehabilitation Medicine, at the National Institutes of Health, Clinical Center.
