Research Activities

In our mission to create knowledge through research, the Division of Gastroenterology and Hepatology continues to conduct cutting-edge investigations of the molecular, cellular, and physiological conditions of healthy and diseased states of the gastrointestinal tract, liver, and pancreas. The central piece of the Division's research endeavor is the NIH-funded University of Michigan Center for Gastrointestinal Research, which encompasses three thematic areas of research:

  1. neurobiology of appetite control and visceral pain;
  2. molecular and cellular mechanisms of inflammation; and
  3. cell growth, differentiation, and programmed cell death.

With the critical support of the Center, research funding for the Division of Gastroenterology and Hepatology has increased dramatically over the last several years, now totaling over $15 million including over 50 individual grants from the NIH and other federal funding agencies.
