Dr. Zaha is originally from Romania, where he received his initial medical training at Carol Davila University. From there Dr. Zaha went on to conduct research studies of myocardial cell biology investigating insulin signaling and glucose transport mechanisms in the heart and obtained a PhD degree summa cum laude at University of Freiburg in Germany. He next completed a postdoctoral fellowship in molecular biology and genetics at University of Utah, conducting 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 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 his internal medicine residency at Indiana University and cardiology fellowship at Yale and University College London, specializing clinically in onco-cardiology and advanced cardiovascular imaging.
Dr. Zaha joined the cardiology faculty at UT Southwestern in January 2016, where he is currently Assistant Professor in a clinical scholar position that aims to interface basic and clinical science. Dr. Zaha brings a unique combination of interests and expertise in fundamental scientific methods, biological imaging tools and patient-centered clinical cardiac care. Dr. Zaha reopened dedicated onco-cardiology clinics at UT Southwestern and is actively involved in the clinical imaging labs. Dr. Zaha aims to develop noninvasive, nonradioactive biochemical imaging of the human heart metabolism for early detection and better understanding of myocardial disease in the Advanced Imaging Research Center (AIRC) at UT Southwestern.
Dr. Zaha’s interests beyond science and medicine include his family, friends, outdoors sports and the exploration of nature and the arts.
