Gastroenterology Fellowship Program

The aim of the Gastroenterology Fellowship Program is to advance the understanding, diagnosis, treatment and prevention of diseases of the gastrointestinal and hepatobiliary systems. Upon completion of the training experience, trainees will have the clinical, investigative and teaching skills necessary to take a leading role in academic and clinical gastroenterology.

Fellowship Tracks

There are three fellowship tracks within the program.

The first year of each track is identical and composed of inpatient clinical rotations on the gastroenterology consult services at The Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center, inpatient endoscopy and the inpatient hepatology service.

Clinical Scholar: This three-year track is geared toward fellows who wish to become academic clinicians and educators. Years two and three consist of limited inpatient rotations, outpatient endoscopy, continuity clinic and subspecialty clinics. The fellow will have the opportunity to focus on a particular clinical area such as inflammatory bowel disease, therapeutic endoscopy, neurogastroenterology, nutrition, gastrointestinal neoplasia or liver disease. The fellow will engage in a clinical research project within that area of interest, and will be asked to identify a clinical mentor.

Physician Scientist: This three-year track is aimed at training fellows for independent investigative careers in laboratory investigation in gastroenterology or hepatology.

After the first year of clinical rotations, the fellow will select a research mentor and focus on a specific area of investigation. The research section provides information on the division’s current research. The fellow will continue to have limited inpatient rotations, as well as outpatient endoscopy, subspecialty and continuity clinic during years two and three.

Clinical Investigator: This four-year track culminates in either a Master of Health Science (MHS) in Clinical Investigation or a Ph.D. in clinical investigation from the Johns Hopkins Bloomberg School of Public Health. After the first year of clinical rotations, the fellow will spend the second year dedicated to classroom training and clinical research at the School of Public Health; clinical responsibilities are suspended during this year. Years three and four consist of continued research time, as well as limited inpatient rotations, outpatient endoscopy, subspecialty and continuity clinic.

Clinical Rotations

The clinical rotations include inpatient rotations, outpatient rotations and endoscopy.

Inpatient rotations:

In all tracks, the fellow will rotate on the four clinical services during the first year:

  • GI Consult Service at The Johns Hopkins Hospital
  • GI Consult Service at Johns Hopkins Bayview Medical Center
  • Liver Inpatient and Consult Service
  • Endoscopy Service at The Johns Hopkins Hospital

Outpatient rotations:

All fellows spend one half-day per week in Continuity Clinic with a GI faculty preceptor.

Upper level fellows will also rotate through various subspecialty clinics to allow exposure to a variety of GI subspecialty areas.

Endoscopic training:

Fellows will be trained in the ACGME-required procedures for gastroenterology. First-year fellows primarily learn endoscopy in the inpatient setting. During second and third year, upper level fellows will rotate through various endoscopy blocks in hospital-based endoscopy settings and ambulatory surgical centers.


Fellows are expected to attend several weekly conferences, including Fellow Didactics, GI Grand Rounds, Journal Club, Morbidity and Mortality Conference, Hepatology Conference and Inflammatory Bowel Disease Conference.
