Biography

Dr. Park received both his undergraduate and graduate degrees in Electrical Engineering. His doctoral work at Stanford University was focused on technical developments of magnetic resonance imaging (MRI) and spectroscopic imaging (MRSI) with application to preclinical glioma brain tumor metabolism. Following completion of his Ph.D. in 2012, he broadened his research into advanced biomedical imaging as a postdoctoral research fellow and a research associate in the Department of Radiology at Stanford School of Medicine. He joined the UT Southwestern as an Assistant Professor in 2016.

Dr. Park's lab has been focused on methodological developments and clinical translation of metabolic imaging, particularly of mitochondria, enabling in vivo assessment of metabolic fluxes in individual enzyme-catalyzed reactions. As metabolic processes and their regulation are complex, numerous transient physiological conditions, including nutritional states and exercise, impact metabolism. Chronic diseases such as cancer and type 2 diabetes may also have profound effects. For accurate and selective imaging of metabolism and function of interests, his lab develops imaging concepts and schemes by developing a network of ideas in MR pulse sequence, physiology, chemistry, and clinical translation.
