Dr. Engelking is originally from Houston, Texas and first came to UT Southwestern for joint MD/PhD training (2000-2007), where he studied cholesterol and fat metabolism under the tutelage of Nobel Laureates Goldstein and Brown. He then completed his clinical training in internal medicine at Massachusetts General Hospital (2007-2010), an affiliate of Harvard Medical School.  Drawn by the opportunity to study lipid metabolism in the intestine, he returned to UT Southwestern for clinical and research fellowships in gastroenterology and hepatology (2010-2014) and thereafter joined the faculty of the Departments of Internal Medicine (Division of Digestive and Liver Diseases) and Molecular Genetics along with the Center for Human Nutrition. His current research interests include understanding the roles that lipids, particularly cholesterol, play in the growth of intestinal cells both in normal health and in states of uncontrolled growth, such as intestinal cancers like colorectal cancer.

He practices adult gastroenterology and serves as a teaching attending of fellows, residents, and students at Parkland Memorial Hospital.  He also serves as the director of GI genetics clinic at Parkland and at UT Southwestern, which is focused on the care of patients with either known or suspected inherited disorders of polyposis and colorectal cancer, including Lynch syndrome, Familial Adenomatous Polyposis syndrome, Peutz-Jeghers syndrome, Juvenile Polyposis syndrome, and Cowden syndrome.
