Dr. Bray holds the Susan T. Jastrow Endowed Chair in the Department of Nutritional Sciences at the University of Texas at Austin, with a master’s degree in Exercise Physiology and a PhD in Human and Molecular Genetics. Dr. Bray’s research focuses on the relationship between genetic variation, energy balance, and lifestyle factors such as exercise, nutrition, and circadian patterns of behavior. Work in her laboratory is designed to identify the mechanisms by which timing and quality of energy intake affects weight gain and metabolic health, in particular through intestinal absorption and the gut microbiome. Dr. Bray also currently leads one of the largest genetic studies of exercise adherence established to date, the Training Interventions and Genetics of Exercise Response (TIGER) study, with a total cohort of more than 3,500 individuals. Dr. Bray's research has included investigations of aerobic fitness and resting and exercise energy expenditure in children and adolescents and clinical studies of morbidly obese adolescents undergoing bariatric surgery.
