Pediatric Gastroenterology/Nutrition Fellowship

About The Fellowship

The Division of Pediatric Gastroenterology and Nutrition at Weill Cornell Medicine offers a three-year fellowship that is approved by the Accreditation Council for Graduate Medical Education (ACGME). Our campus is located in the NewYork-Presbyterian Phyllis and David Komansky Children’s Hospital on the Upper East Side of Manhattan. Our multidisciplinary team approach provides the highest level of care to the child and their family with all aspects of GI pathology.

The goal of this fellowship program is to provide fellows with the best clinical and research experience available in preparation for a successful career in academic gastroenterology. The program accomplishes this goal by providing a structured clinical and educational curriculum as well as a research curriculum tailored to the interest of the fellow.

Clinical Program Description

The fellowship is a 3 year program that provides an estimated 18 months of clinical training and 18 months of research experience.

The inpatient team service provides consultative services to the NICU, PICU and Pediatric Inpatient unit.

We are affiliated with the top ranked NewYork-Presbyterian Phyllis and David Komansky Children’s Hospital at Weill Cornell Medicine and the NewYork-Presbyterian Center for Advanced Digestive Care (CADC), one of the nation's leading centers for the diagnosis and treatment of childhood digestive diseases. 

Our program provides comprehensive care to diagnosis and treatment of patients with disorders including:

  • Inflammatory Bowel Disease
  • Gastrointestinal motility problems and Functional GI complaints
  • Eosinophilic Esophagitis and other Allergic GI Disorders
  • Pancreatic Disease
  • Celiac Disease
  • Diarrhea
  • Gastroesophageal Reflux Disease
  • Hepatobiliary Disease
  • Feeding Disorders and Nutritional Deficiencies

Fellows gain clinical experience through the care of patients at our comprehensive treatment programs including:

Pediatric Inflammatory Bowel Disease (IBD) Program

Pediatric Motility Program

Eosinophilic Esophagitis Program

Pediatric IBD Transition of Care Program


The philosophy of the clinical time is to concentrate it in the first year and maintain clinical expertise in the second and third year while allowing time to focus on the research component of the program during the latter years.

Our trainees spend one month per year on the inpatient and inpatient service for both liver and small bowel transplantation at the New York Presbyterian Morgan Stanley Children’s Hospital campus.

First Year

  • Inpatient -9 months
  • Liver - 1 month
  • Research - 1 month

Second Year

  • Inpatient - 2 months
  • Liver - 1 month
  • Research  - 8 months
  • Elective (optional) - 1 month

Third Year

  • Inpatient - 1 month 
  • Research  - 10 months
  • Elective (optional)- 1 month

Fellows take home call throughout the year on a rotation divided among the other fellows.

Outpatient Clinics

In the first year, the fellow is required to attend 2 half day clinic sessions per week. In the second and third years, the fellows attend 1 half day clinic per week. In addition, the second and third year fellows have 6 weeks outpatient clinic rotation during which they attend 6 outpatient sessions per week to enhance their abilities to comprehensively care for the complicated patients involving multidisciplinary teams.


We offer expertise and training in procedural skills including Upper endoscopy, Colonoscopy, Therapeutic Endoscopy (banding, scleroses, cautery, clipping, balloon dilation), Suction Rectal biopsy, Percutaneous Endoscopic Gastrostomy placement, Paracentesis, Liver Biopsy, Esophageal Manometry, Anorectal Manometry, pH Impedance, Bravo capsule, Wireless capsule endoscopy, Hydrogen and Methane Breath testing.

Advanced procedures including ERCP and Endoscopic Ultrasound are performed by the Advanced Endoscopy Team of the CADC.

All fellows perform procedures in the Pediatric Unit for Procedural Sedation (PUPS) one half day session per week.

Fellows have the unique ability to practice and strengthen their skill with the use of our GI Endoscopy Simulator. Fellows can practice basic skills such as managing a loop in the colon, as well as practice more rare procedures such as esophageal banding


The educational curriculum is a structured program consisting of lectures, seminars, invited speakers, journal clubs, and visiting professors. Through the course of three years, a thorough review of gastrointestinal physiology is completed. Fellows actively participate in the educational series.

There have been major research developments at Weill Cornell Medicine over the past few years.  A generous $25 million gift established the Gale and Ira Drukier Institute for Children's Health .  This institute is devoted to bench-to-bedside research to advance new treatments and therapies that target childhood diseases and disorders.  Additionally, through the generosity of Jill Roberts and the Jill Roberts Charitable Foundation, the Jill Roberts Institute for Research in Inflammatory Bowel Disease was established to accelerate new scientific discoveries, enabling personalized translational medicine to better prevent and treat inflammatory bowel disease in patients. In addition, our Division received over $3 million in funds from the NICHD/NIH to lead a multicenter study examining statural growth in pediatric Crohn’s disease. Through these major developments and already existing research infrastructure, there are numerous opportunities for outstanding research experiences and mentorship. Fellows will have opportunities for rigorous formal and informal clinical, translational, and basic research training in a wide variety of areas within the Division, Department, and Medical College.
