Walter R. Witschey, PhD

Dr. Walter Witschey is Associate Professor of Radiology, Associate Vice Chair of Research IT, and Director of the Advanced Cardiovascular Imaging Lab at the University of Pennsylvania. His core research focus is cardiac magnetic resonance imaging (CMR), imaging technologies and artificial intelligence. His lab uses a multidisciplinary and translational approach, integrating techniques from electrical engineering, computer science, biology and bioengineering. Our techniques include MR physics and pulse sequence development (T1ρ and quantitative susceptibility mapping / QSM) and MR spectroscopy (1H downfield MRS), non-proton imaging and spectroscopy (23Na and 31P), machine learning and computer vision, and closed-loop systems for medical imaging. His translational research interests are in myocardial ischemia and coronary artery disease, reperfusion injury, non-ischemic heart disease, congenital heart disease and metabolic imaging of the heart. He has mentored more than 25 predoctoral students, 7 graduate students, and 5 postdoctoral fellows across multiple departments of Radiology, Bioengineering and Electrical Engineering since he was appointed to the faculty at Penn.
