Robert W. Summers, M.D.
James A. Clifton Professor (Emeritus) and Director of Clinical Programs for the Gastroenterology Division

Dr. Summers is well known for his work on small bowel motor activity. He has studied the effects of irradiation on the smooth muscle of both the small and large intestine.   His ongoing clinical studies include the examination of therapeutic agents in motility disorders and inflammatory bowel disease; aspirin and folic acid in the prevention of colonic polyps; and the effects of exercise on intestinal function.

Dr. Summers is particularly interested in gastrointestinal motility disorders; mechanisms of injury in radiation enteritis; colon cancer; and inflammatory bowel diseases.
