    David Dubowitz, MD PhD, is a radiologist and neuroscientist. He received his bachelor and master degrees in Electrical Engineering from the University of Cambridge, England. His medical training was at University of Oxford, England, and he has completed residencies in Internal Medicine at Oxford, and Radiology at Cambridge. He is also did a fellowship in Magnetic Resonance Spectroscopy at Huntington Medical Research Institutes in Pasadena, CA. His PhD is from California Institute of Technology where he also did postdoctoral research on functional MRI of cerebral physiology in the primate brain.

    He joined the UCSD faculty in 2002, working primarily at the UCSD Center for Functional Magnetic Resonance Imaging, where he serves as Associate Director. His primary research interests are is in the field of magnetic resonance imaging, focusing on the basic physiology of functional MRI, both in humans and in other animals, and MRI measurements of cerebral blood flow and metabolism, particularly as they apply to acclimatization and deacclimatization to hypoxia at altitude. He also has research interests in MRI measurements of pulmonary blood flow, and in magnetic resonance spectroscopy (MRS).
