Dr. Williams joined Texas State University in the fall of 2009 and is affiliated with the Exercise and Sports Science Division. Immediately prior to his appointment at Texas State, he served as Associate Chair/Associate Professor at Texas Tech University in the Department of Health, Exercise and Sport Sciences, and held a joint appointment within the Department of Physiology at the Texas Tech University Health Sciences Center. Previous positions include academic and professional appointments at The University of Texas Health Sciences Center at Tyler, The Institute for Exercise and Environmental Medicine-Dallas, The University of Arizona Health Sciences Center, Texas Christian University and The University of Mississippi. He is a fellow of the American College of Sports Medicine and a member of the American Physiological Society. His research interests include: cardiopulmonary limitations to human performance; respiratory muscle fatigue and training; physiological gender differences and aging; and neurotrophin responses to exercise. He has received grant funding to support his research from the NIH, the American Lung Association and state foundations. His work has been published in journals such as Chest, Journal of Applied Physiology, Journal of Physiology and Medicine and Science in Sports and Exercise. Dr. Williams lives outside of San Marcos with his wife Jana, a practicing attorney.
