The Division of Gastroenterology provides evaluation and diagnosis for infants, children and adolescents with diseases involving the gastrointestinal tract and/or liver as well as nutrition support services.

Education and Training

Our division is actively involved in the education of both residents and medical students. Our fellows play an integral role in educating these rotating trainees.


We sponsor an Accreditation Council of Graduate Medical Education (ACGME)-accredited fellowship training program. We accept two fellows per year into our three-year program.


Residents in the gastroenterology rotation observe and perform procedures, perform consultations on hospitalized children and attend clinic sessions.


Our faculty conduct basic and clinical research, publish their research results in nationally recognized journals and contribute to national policy. We are committed to work that will uncover the causes of diseases, find treatments for diseases and study the effect of medications on diseases. Our research program is focused on molecular immunology.

Ongoing research projects include:

  • mechanism and regulation of gastric acid secretion
  • using gastric parietal cell model to study general cell biology
  • pathogenesis of nonalcoholic steatohepatitis (NASH)
  • pathogenesis of inflammatory bowel diseases (IBD)

Clinical Care

We specialize in the diagnosis and treatment of nutritional problems, gastrointestinal problems, (including inflammatory bowel disease, reflux disease, diarrhea, constipation, peptic diseases, Crohn's disease, celiac disease, and eosinophilic esophagitis) and liver diseases (including hepatitis B and C, autoimmune hepatitis, metabolic liver diseases, preparation for and follow-up after transplant).
