The Division of Gastroenterology at Washington University School of Medicine performs cutting-edge molecular and translational research.
We have a diverse research base with physician-scientists (MD and MD/PhD) and PhD scientists conducting basic investigation into the molecular regulation of development, nutrient absorption, colon carcinogenesis, immune tolerance and inflammation and repair.
In addition, we conduct a range of active translational research, including novel therapies for inflammatory bowel disease, obesity and energy metabolism, hepatic steatosis, hepatitis C and topographic manometric assessment of esophageal motility.
