Dr. Dietschy received his medical degree from Washington University School of Medicine in Saint Louis, Missouri. He completed his internship and residency training in internal medicine in Denver, Colorado. Subsequently, Dr. Dietschy served as a postdoctoral research fellow in gastroenterology at Boston University School of Medicine at Massachusetts Memorial Hospital and then had additional training in lipid biochemistry and metabolism as a research fellow at the University of Texas Southwestern Medical Center at Dallas. He has been on the faculty of the Department of Internal Medicine at UT Southwestern since 1965. He served as chief of the Division of Gastroenterology from 1979 to 1998 and as chief of the Division of Digestive and Liver Diseases from 1999-2002. His research has generally been in the area of regulation of cholesterol absorption and sterol metabolism. His recent research interests have involved the mechanism of action of a number of different ABC transporters on moving cholesterol across membranes, in newer pathways for bile acid synthesis and in understanding the mechanisms of regulation of cholesterol balance across the brain. He has authored more than 200 research publications in various professional journals including the Journal of Biological Chemistry, Science, Neuroscience, Current Opinion in Lipidology and the Journal of Lipid Research.
