Luke Szweda , Ph.D., is a Professor in the Department of Internal Medicine at UT Southwestern Medical Center, and a member of its Division of Cardiology.

Originally from Wisconsin, Dr. Szweda holds a bachelor’s degree with honors in chemistry from Carleton College in Northfield, Minnesota. He received his doctorate in biochemistry at the University of California, Los Angeles, and completed his postdoctoral training in biochemistry in the lab of Dr. Earl Stadtman at the National Institutes of Health.

Before joining the UT Southwestern faculty in 2017, Dr. Szeda served on the faculty at Case Western Reserve University and at the Oklahoma Medical Research Foundation, where he was chair of the Aging and Metabolism Research Program.

Dr. Szweda’s research focuses on mechanisms by which diet and age change cardiac and mitochondrial metabolism, influence the redox status within cardiomyocytes, and affect insulin resistance and cardiovascular disease.

His investigations have resulted in more than 130 publications in peer-reviewed journals. Additionally, he has presented his findings at scientific conferences throughout the United States and around the world.

Dr. Szweda is active in several professional organizations, including the American Society of Biochemistry and Molecular Biology, the American Association for the Advancement of Science, the American Chemical Society, and the American Heart Association.
