The Division of Gastroenterology, Hepatology and Nutrition has active clinical research efforts aimed at developing innovative methods for improving the health of children with disorders of the gastrointestinal tract, liver and pancreas. Pediatric pancreaticobiliary disorders, inflammatory bowel disease, and Crohn's disease are only a few of the many areas of focus. Collectively, these programs foster frequent interaction among faculty within the Division, the Department, and the Duke University School of Medicine.

With funding from the National Institutes of Health and industry, members of the Division also participate in multiple clinical studies. Investigators are working to advance potential therapies for many childhood liver diseases in addition to ulcerative colitis and Crohn’s disease. Other research activities include participation in local and national registries to gather data about outcome and treatment of children with inflammatory bowel disease.
