Research Interests: exercise nutrition, vitamin D and physical activity, nutrition and sports performance


Dr. Horvath has taken a circuitous pathway to his current research interests and present location. After growing up in Santa Barbara during the 60’s and 70’s, he went to the University of California at Irvine when it was still in the middle of a cattle ranch. He received his BS in Biology with specialization in Ecology and Systematics. His undergraduate research was on defensive secondary plant compounds and the herbivore (insect) interaction. To move up to larger animals, Dr. Horvath traveled to Upstate New York and went to graduate school at Cornell University in Ithaca. The subjects of his next research were larger – his MS thesis was on the Nutritional Ecology of White-tailed Deer. Getting closer to home, he shifted again doing a PhD dissertation on Dietary Fiber Analysis and Human Colonic Fermentation. After a post-doc with Dr. Milton Weiser and Michael Duffy on large intestinal nutrient absorption and electrophysiology at the University at Buffalo, he joined the faculty of the Nutrition Program. Since being in the Nutrition Program, which is now part of the Department of Exercise and Nutrition Sciences, his teaching has focused on carbohydrate nutrition, exercise nutrition, general education undergraduate nutrition and lectures on nutrition to medical students. He is actively involved in distance learning and international education with the UB program at Singapore Institute of Management. His research has evolved into the area of exercise nutrition as it relates to cardiovascular health and athletic performance (endurance, cognition and injury prevention) and prevention of cancer, specifically prostate. Dr. Horvath’s research on dietary fat and exercise performance has been extensively covered in the lay press.  He has adjunct appointments in Department of Physiology and Biophysics and the School of Nursing.
