Gregory D. Kennedy, MD, PhD Print Friendly Page

Faculty, University of Wisconsin School of Medicine and Public Health

Gregory D. Kennedy, MD, PhD, earned his medical degree from the University of Washington in Seattle and completed his residency in general surgery at University of Wisconsin Hospital and Clinics, followed by a fellowship in colon and rectal surgery at Mayo School of Graduate Medical Education.


Dr. Kennedy is certified by the American Board of Colon and Rectal Surgery and by the American Board of Surgery. He is also a fellow in the American College of Surgeons and the American Society of Colon and Rectal Surgeons. He specializes in the surgical treatment of colon and rectal cancer, inflammatory bowel disease - such as Crohn’s and ulcerative colitis - diverticulitis, benign conditions of the colon, rectum and anus, minimally invasive and laparoscopic approaches to diseases of the colon and rectum and endoscopic treatment of colonic disease.

Research in the colon and rectal surgery laboratory focuses on two basic problems. First, we are interested in gaining a better understanding of the relationship between colon and rectal cancer and various environmental exposures. To this end, we are trying to gain insight into the role of PAS proteins, a family of proteins responsive to environmental stimuli, in the origin and disease development of colon and rectal cancer. Second, we employ various molecular and microscopic techniques to provide insight into those features of colon and rectal cancer that may correlate with response to treatment, recurrence, and survival.
