Vlad Gabriel Zaha, M.D., Ph.D., is an Associate Professor of Internal Medicine at UT Southwestern Medical Center, and a member of its Cardiology Divsion. He specializes in cardio-oncology and advanced cardiovascular imaging diagnostic modalities.

Dr. Zaha earned his medical degree at Carol Davila University of Medicine & Pharmacy in Bucharest. He went on to conduct research studies of myocardial cell biology, investigating insulin signaling and glucose-transport mechanisms in the heart.

He earned his doctoral degree summa cum laude at the University of Freiburg in Germany and completed a postdoctoral fellowship in molecular biology and genetics at the University of Utah, where he conducted studies to elucidate molecular and genetic connections that underlie the energetic metabolism in the heart, funded by a fellowship award from the American Heart Association. Dr. Zaha also conducted studies of molecular mechanisms for protection of myocardial mitochondria and was recognized as a finalist at the 2014 Northwestern Young Investigator Forum.

Dr. Zaha completed a residency in internal medicine at Indiana University and a fellowship in cardiology at Yale University and University College London, specializing in cardio-oncology and advanced cardiovascular imaging.

He joined the UT Southwestern faculty in 2016.

Since March 2018, Dr. Zaha has served in the leadership council of the Cardio-Oncology Section of the American College of Cardiology. Other professional organizations in which he is active include the American Heart Association, the American Society of Echocardiography, the American Society of Nuclear Cardiology, the Society for Cardiovascular Magnetic Resonance, and the International Society for Magnetic Resonance in Medicine.
