Gastroenterology​/Hepatology


The Gastrointestinal and Liver Disease Specialty Research Network is a multi-disciplinary group of clinician-investigators that evaluates clinically important questions to inform new treatments and new approaches for care in diseases of the pancreas, liver, biliary (gallbladder) system, stomach, small bowel, and colon.  These include inflammatory, infectious, malignant, and immune-related disorders. The group’s investigations are supported by several sources including The Permanente Medical Group, the National Institutes of Health, the National Cancer Institute, the Patient-Centered Outcomes Research Institute, and private non-profit foundations.
