At UMHB, Dr. Willoughby is a Professor of Anatomy and Physiology in the Physician Assistant (PA) Program where he teaches human gross anatomy and human physiology to the first-year medical students. He also teaches applied research and evidence-based research to the PA students. He is also a Professor of Exercise Physiology and Nutrition in the School of Exercise and Sport Science where he teaches undergradute exercise physiology and graduate clinical exercise physiology and advanced exercise physiology, and is also involved in research in the Human Performance Laboratory. Presently he holds graduate faculty appointments at Baylor University, Texas A&M Health Science Center, Texas A&M University-Corpus Christi, and the University of Central Florida.
Prior to UMHB, Dr. Willoughby was a Professor of Exercise and Nutritional Biochemistry and Molecular Physiology at Baylor University in Waco, TX where he taught graduate level, nutritional biochemistry, exercise physiology, exercise biochemistry, muscle physiology, and exercise endocrinology classes. He was also the founder and director of the Exercise and Biochemical Nutrition Laboratory. At Baylor, he also held secondary faculty appointments in the Department of Biology and Department of Biomedical Science.
Dr. Willoughby has over 150 publications in scientific peer-reviewed research journals such as Medicine and Science in Sports and Exercise, Journal of the International Society of Sports Nutrition, International Journal of Sports Nutrition and Exercise Metabolism, Applied Physiology, Nutrition, and Metabolism, Nutrition Research, and the Journal of Strength and Conditioning Research. He has also authored and co-authored several book chapters on issues related to exercise and sports nutrition. He also has over 100 research-related presentations. He serves as the Editor-in-Chief for the Journal of Nutrition and Food Engineering and the International Journal of Kinesiology and Sport Science. He is also an Associate Editor for the Journal of Sports Science and Medicine, the Journal of Strength and Conditioning Research, Nutrients, and Fronteirs in Nutrition.
Dr. Willoughby is internationally renowned for being an active scientific contributor to the field of resistance training and exercise/sports nutrition. In addition to being highly sought for national and international speaking engagements relative to resistance training and sports nutrition, Dr. Willoughby has previously contributed to Muscle and Fitness, Flex, The Sports Nutrition Insider, Men’s Health, and has been featured on many podcasts and radio programs such as the Performance Nutrition Show. He has served as a nutrition and supplementation consultant for many nutrition/sport supplement companies.
Dr. Willoughby has previously worked as a collegiate strength and condition coach and presently serves as a resistance training and conditioning consultant for high school, collegiate, and professional athletes. In addition, he also consults with amateur and professional bodybuilders relative to their training and nutritional program.
Personally, Dr. Willoughby played college and semi-pro football and semi-pro baseball. He is currently a competitive Masters’ level bodybuilder and serves as a bodybuilding judge for the International Federation of Body Building (IFBB).
Dr. Willoughby’s primary research focus is on the skeletal muscle molecular and signaling mechanisms regulating the effectiveness and efficacy of nutritional supplements and nutritional intervention [aka. nutrigenomics (nutrient-gene interactions). He is also interested in attempting to find ways of helping to combat sarcopenia in the elderly using exercise and/or nutritional interventions.
