Robert Roach, PhD, is Director of the Altitude Research Center (ARC) at the University of Colorado School of Medicine. His current research includes projects in high altitude medicine and physiology, and exercise performance. Current funding includes major support from the Department of Defense. He currently oversees a staff of postdoctoral fellows and research assistants working on projects to predict who is susceptible to altitude illness, and the molecular mechanisms of acclimatization to hypoxia. Dr. Roach is a Fellow of the American College of Sports Medicine, and serves on the editorial boards for Journal of Applied Physiology and High Altitude Medicine and Biology. He also co-directs the International Hypoxia Symposia, the premier meeting of scientists dedicated to understanding the effects of hypoxia on the human body.
