About Dr. Hill

Bradford Hill

Bradford Hill, Ph.D.
Professor of Medicine

Bradford G. Hill, Ph.D., is a Professor in the Department of Medicine and Division of Environmental Medicine, and a University Scholar at the University of Louisville. The focus of Dr. Hill's research is to understand how changes in metabolism contribute to cardiometabolic health and disease. In particular, his studies focus on how glucose metabolism and mitochondrial activity influence pathological cardiac remodeling as well as how changes in metabolism underlie adaptations to physiological stressors such as exercise. Recent work from Dr. Hill's laboratory shows that exercise-induced periodicity in cardiac glucose utilization regulates physiologic cardiac growth. His group is also examining metabolic mechanisms of cardiomyocyte proliferation and how metabolic changes in cardiac mesenchymal cells (e.g., fibroblasts) influences cardiac repair and remodeling after myocardial infarction. In addition, working with collaborators in the Center, Dr. Hill is examining how exposure to particulate air pollution influences metabolism and cardiometabolic health..

Dr. Hill serves or has served as a peer reviewer for the National Institutes of Health (NIH), Congressionally Directed Medical Research Program (CDRMP) / Department of Defense (DoD), the American Diabetes Association (ADA), and the American Heart Association (AHA); he has also served as a peer reviewer for numerous international funding agencies. Dr. Hill is currently a member of the Editorial Boards of Circulation Research, American Journal of Physiology – Heart and Circulatory Physiology, Journal of Molecular and Cellular Cardiology, and Redox Biology, among others. He has authored or coauthored over 100 peer-reviewed articles.
