Dr. Douglas Robertson is a Professor of Medicine at the Geisel School of Medicine at Dartmouth, where he is a Gastroenterologist with research interests both in the epidemiology of colorectal cancer and the utility of screening and surveillance for colorectal cancer. He has used large data sets to understand the associations of factors (like drugs and diet) on the development of colorectal neoplasia. He also has studied the effectiveness of colonoscopy in the prevention of colorectal cancer in those with a prior history of neoplasia.
Dr. Robertson is also the Chief of Gastroenterology at the VA Medical Center in White River Junction, VT.
