Fellowship Program | Gastroenterology

The Gastroenterology training program mission is to:

  • Educate tomorrow's gastroenterologists within a multidisciplinary and interdisciplinary environment drawing from a diverse patient population to prepare them for a lifetime of learning, leadership and contribution.
  • Guide gastroenterology fellows in utilizing self-reflection and self-improvement to encourage sustained health and wellness
  • Train gastroenterology fellows to deliver excellence in health care, emphasizing critical thinking and the creation and implementation of new knowledge and cutting-edge technologies.

OHSU's Gastroenterology training program's goal is to provide you with an outstanding education in both Gastroenterology and Hepatology in a collegial, supportive and academically challenging environment. In the sections below, we have provided you with information on the application process, program overview and listing of current fellows.

Program | Gastroenterology

First year training

The first year primarily entails inpatient clinical responsibilities on the consultative services at OHSU and the Portland VA Medical Center. While on the GI Consult Service, the fellow is part of a team that includes a GI attending and a medical resident. The team is responsible for performing GI consultations for patients on the medical and surgical services. The duties of the fellow include the supervision and direction of the service, and the instruction of the house staff and students in basic aspects of Gastroenterology. The fellow is supported by full-time faculty members who serve as resources for any questions, problems or procedures that are required day or night. In addition, for the first month, the first-year trainee is accompanied by a second-year fellow to help him/her ease into the new environment. The program is structured to develop strong bonds between the fellows and faculty members, resulting in the best teaching and patient care possible.

Our first-year fellows also spend a total of two outpatient months at Kaiser Permanente as a consulting Gastroenterologist to obtain experience in the private practice of Gastroenterology.

The first-year fellow will obtain extensive experience in diagnostic as well as therapeutic upper and lower endoscopic procedures. Emphasis is placed on the appropriate application of endoscopy as well as the attainment of technical skills. During the first three months of fellowship, the Summer Core Lecture series is presented twice weekly by members of the GI/Hepatology faculty, the surgery faculty and a variety of other services. Topics include:

  • Introduction to endoscopy
  • Stress management during fellowship
  • Basics of GI Pathology
  • Management of GI bleeding
  • Inflammatory bowel disease
  • Jaundice
  • Hepatitis C
  • Capsule endoscopy
  • Esophageal manomtery

Second & Third year training

The second and third year of fellowship allow for more time to pursue scholarly activities that are a mandatory part of the program requirements. This may include:

  • Participation in research projects
  • Presentations at national and international Gastroenterology meetings
  • Journal publications.

Each fellow is encouraged to align him or herself with one of the faculty members and participate in research on a topic of joint interest. There is less emphasis on consult rotations. In the latter part of the third year, the fellow serves as the attending on the GI consult service at the University with faculty back-up. This is an experience unique to our program and a significant confidence builder before entering the “real world”.


The fellows attend a number of conferences both within the Division and the Department of Medicine. There is a weekly conference that allows for topics in pathology, hepatology, clinical nutrition and hepatobiliary disease. Every Monday morning, there is a research conference during which research topics and meeting presentations are discussed. There is also training in the critical review of the medical literature. An outstanding medical school library, internet/literature search access, courses and seminars in the basic sciences, statistics and public health courses are also available.
