Dr. Bray’s research focuses on the relationship between energy balance and lifestyle factors such as exercise, nutrition, and circadian patterns of behavior.   Her recent findings related to the genetic underpinnings of exercise adherence and the relationship between timing and quality of energy intake and weight gain/metabolic health have been featured on national and international news programs and a myriad of websites and popular news media.  Dr. Bray 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 planned cohort of more than 5,000 individuals.  Dr. Bray’s research has included investigations of aerobic fitness and resting and exercise energy expenditure in children and adolescents, circadian studies of feeding and metabolic response, and clinical studies of morbidly obese adolescents undergoing bariatric surgery.  Dr. Bray is a nationally recognized expert on the genetics of obesity, energy balance, and exercise response.  She is a Professor in the Department of Nutritional Sciences, with a master’s degree in Exercise Physiology and a PhD in Human and Molecular Genetics.  Prior to joining the University of Texas at Austin, Dr. Bray was Director of the Heflin Center for Genomic Sciences Genomics Core Laboratory at the University of Alabama at Birmingham and the Children’s Nutrition Research Center/Baylor College of Medicine Genetics Core Laboratory.  Dr. Bray has published extensively in a wide range of peer-reviewed journals, and her work has been featured in national and international scientific meetings.
