Mission Statement

We strive to guide our fellows as they develop into independent practitioners and scholars who will shape the field of pediatric gastroenterology. We work closely with each fellow to identify and cultivate their strengths and career goals, and to develop the clinical, procedural, and scholarly skills necessary to pursue a career as an academic pediatric gastroenterologist.

The program provides broad clinical experience in outpatient and inpatient medicine, excellent procedural training, and in-depth didactics. Fellows consult on a broad range of clinical gastrointestinal problems including inflammatory bowel disease, cystic fibrosis, celiac disease, liver disorders, pancreatic disorders, motility and functional disorders, intestinal rehabilitation, and nutritional disorders.

Trainees benefit from the diverse clinical population seen at a major referral center, with consultations ranging from outpatient referrals to quaternary level inpatient care. Through numerous clinical conferences, fellows are exposed to the in-depth didactics necessary for up-to-date clinical care. In addition to gaining proficiency in outpatient and inpatient pediatric gastroenterology, fellows are also provided extensive training in basic and advanced procedures.


Rigorous scholarly work is an integral component of the training experience, and Columbia University Irving Medical Center offers a wealth of opportunities. Fellows are expected to participate in basic, clinical, or translational investigative projects and to produce high quality scholarship under the close supervision of an established faculty mentor. Through regular committee meetings faculty members monitor and aid fellows in the progress of their scholarly endeavors. The majority of our fellows are supported by extramural funding including an NIH T32 Training Grant in Gastroenterology.


Fellows participate in divisional grand rounds, case conference, and weekly didactic sessions as well as interdisciplinary conferences with radiology, pathology, adult gastroenterology and pediatric surgery.  In addition, fellows participate in bedside, case-based and didactic teaching sessions with residents and medical students.

Why Columbia?

Our program and hospital allow fellows to provide care to a patient population with unparalleled variety and acuity, while gaining a solid foundation in “bread and butter” pediatric gastroenterology.  Fellows have exposure to all facets of the field, with particularly strong training in hepatology, neurogastroenterology and motility, and celiac disease, and perform cutting-edge procedures using state-of-the-art technology.  Columbia University Irving Medical Center offers myriad basic, translational and clinical research opportunities.  Fellows get to live and play in New York City, and most importantly work with a diverse, vibrant and caring group of people.


Residents are employees of NewYork-Presbyterian Hospital and affiliated with Columbia University Irving Medical Center. With these affiliations come many benefits!
