Pediatric Gastroenterology Fellowship

Welcome to the Pediatric Gastroenterology, Hepatology, and Nutrition Subspecialty Fellowship Program.

Our fellowship is a 3-year program that provides trainees with clinical, research and educational opportunities. The first year of fellowship focuses on building clinical experience, with the final two years focused on research. Throughout training, fellows are exposed to a breadth of gastrointestinal, hepatic, and nutritional disorders of varying complexity. Fellows rotate on our inpatient hospital service as well as maintain their own half-day outpatient clinic weekly. Our fellows become adept at endoscopies quickly within their first year of training and are exposed to a variety of additional procedures including video capsule endoscopy, percutaneous liver biopsy, motility, esophageal pH-metry, esophageal impedance and gastrostomy tube placement.

Fellow’s primarily spend their time at Connecticut Children’s Medical Center which is the only free standing children’s hospital in the state of Connecticut, and serves as the home of the UConn Department of Pediatrics. Connecticut Children’s is a 187 bed facility designated Level 1 Trauma Center, which includes a Pediatric ER, PICU and NICU, all of which provide extensive clinical exposure to our learners. It hosts a Pediatric Residency Program with 60 residents and three chief residents, and seven other pediatric medical and surgical fellowship programs.

The Connecticut Children’s Division of Digestive Diseases, Hepatology, and Nutrition is headed by Dr. Jeffrey Hyams, a world renown expert in inflammatory bowel diseases and functional gastrointestinal disorders. The division has 12 physician-faculty members, 3 advanced nurse practitioners and a clinical psychologist. The division is well supported by experienced nurses, registered dietitians, and administrative staff. Connecticut Children's has a full range of pediatric subspecialists on staff, including five pediatric surgeons.

Diversity and inclusion are foundational elements of the University of Connecticut Pediatric Fellowship Programs at Connecticut Children’s. Consistent with this focus we pursue diversity in all its varied expressions, including but not limited to, gender, race, ethnicity, physical ability, sexual orientation, and gender identity; with the goal of providing an educational environment that fosters the success of learners who are representative of the population of Connecticut, and a clinical environment that provides high quality healthcare to the myriad communities of the State.


The mission of the Pediatric Gastroenterology Fellowship Program is to train well rounded pediatric specialists who will improve the health of children and adolescents though clinical excellence, research, teaching, community involvement and advocacy.
