Gastroenterology

The Digestive Diseases and Nutrition Center works to prevent, diagnose and treat gastrointestinal, nutritional, hepatic and pancreatic disease in children from birth through young adulthood.

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

Our faculty makes up the Digestive Diseases and Nutrition Center (DDNC), established in 1976 as one of the first centers in the United States for the treatment of children with gastrointestinal and nutritional problems.

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.

Fellows

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

Residents

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

Research

Our faculty conduct basic and clinical research, publish 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)
