Gastroenterology

Gastroenterology

Digestive disorders and diseases of the liver vary widely but share one common feature: the devastating impact they can have on a person’s health and quality of life. In DCRI’s GI program, clinical-translational and basic science experts come together to seek out bold and creative innovations in the treatment of these complex conditions. This partnership positions Duke University and the DCRI as one of the leading GI and hepatology research centers in the world.

GI Research that Spans the Disease Spectrum

Our GI faculty comprises practicing physicians in Duke’s GI division, which ranks among the leading clinical programs in the country. They partner with basic scientists who focus on genetics and genomics, liver injury and repair, endocrinology, metabolism, and the pathophysiologic mechanisms underlying obesity and its complications.

The result of this collaboration is a track record of successful drug development and outcomes research that spans commercial industry, government, and academia. We’ve successfully coordinated more than 60 gastroenterology and hepatology studies, with more than 10,000 patients enrolled across 800 global sites.
