The Pediatric Gastroenterology, Hepatology, and Nutrition fellowship is a three-year, ACGME-accredited program committed to training the next generation of academic pediatric gastroenterologists. The program provides a broad clinical experience in outpatient and inpatient medicine, extensive procedural training, and in-depth didactics. Abundant opportunity is provided for pursuing outstanding multidisciplinary research. Trainees benefit from the diverse clinical population seen at a major referral center, with consultations ranging from outpatient referrals to quaternary-level inpatient care. Numerous clinical and research conferences provide the requisite didactics that are necessary for up-to-date clinical care and research training.

Rigorous scholarly work is an integral component of the training experience, and Columbia University Irving Medical Center offers a wealth of opportunities. Fellows participate in basic, clinical, or translational investigative research and produce high quality projects under the dedicated supervision of an established faculty mentor. The majority of our fellows are supported by extramural funding including a NIDDK T32 Training Grant in Gastroenterology and the prestigious NIDDK-supported K12 Physician Scientist Development Program.
