Stavros Kavouras


Professor Stavros Kavouras is an assistant dean of graduate education and professor of nutrition at Arizona State University. He directs the Hydration Science Lab where he is studying the mechanisms by which water intake impact health and performance. His current research focuses on the effect of water intake on glucose regulation and its implication on children’s hydration and obesity. Kavouras, the author of more than 130 peer review articles and 7,100 citations (h-index 45) has given lectures in 29 countries. He is a section editor of the European Journal of Nutrition and associate editor of Nutrients, Behavioral Medicine and Frontiers in Nutrition. Professor Kavouras is a fellow of the American College of Sports Medicine and the European College of Sports Science as well as elected member of the American Society of Nutrition, the Obesity Society, and the American Physiological Society.
