Research Interests

Dr. Robertson is a Gastroenterologist with research interests both in the epidemiology of colorectal cancer and the utility of screening and surveillance for this disease. 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. Although colonoscopy is increasingly performed, his research suggests that the degree of cancer prevention afforded may not be as great as suggested by earlier studies.

He is past recipient of a VA HSR&D Career Development Award and has served as the Clinical Director of the Polyp Prevention Study Group that has performed large trials examining asprin, folate, calcium and Vitamin D on the prevention of polyps. Currently he is the National Co-Chair of VA Cooperative Study 577 CONFIRM trial. This randomized trial will directly compare up front screening colonoscopy to a strategy of annual stool testing with FIT for the prevention of colorectal cancer mortality in 50,000 US Veterans.
