Dr. Ullman's major research focus is cancer in inflammatory bowel disease. His work includes identification of the clinical risk factors for colon cancer in IBD. He has conducted studies detailing the natural history of dysplasia in ulcerative colitis, the influence of inflammation on carcinogenesis in IBD, and the relative chemopreventive effects of a number of therapies used in UC.  Additionally, Dr. Ullman is pursuing research into biomarkers of disease diagnosis and activity in IBD, and the outcomes of patients with Crohn's disease and ulcerative colitis treated with cyclosporine A.
