Currently led by the Division Director and Clinical Director Mohammad Al-Haddad, MD, the Division of Gastroenterology & Hepatology within the Department of Internal Medicine at IU School of Medicine has a distinguished tradition of innovation in research and education and a demonstrated excellence in patient care. Consistently ranked among the top 15 units nationally by U.S. News and World Report, this is one of the largest divisions of its kind in the United States, offering an enormous breadth of clinical and research expertise for learners and faculty peers.

The Division of Gastroenterology and Hepatology at IU School of Medicine was founded by Dr. Philip Christiansen in 1958 and flourished under the leadership of Drs. Lawrence Lumeng (Division Director from 1984 to 2007) and Glen Lehman (Clinical Director from 1985 to 2005) to national prominence. Under the current leadership, the Division has enjoyed significant growth to faculty and fellowship size, patient and procedural volume, and the federally funded research program. In 2019, the Indiana Center for Liver Research (ICLR) was founded under the leadership of Dr. Gianfranco Alpini.


The division’s research program is extensive and is both laboratory-based and patient-oriented. The group receives millions of dollars in research funding each year from the NIH and other extramural sources.

Our main outpatient surgical center has been named after Dr. Glen Lehman in recognition to his numerous contributions to the field of endoscopy. In addition to our traditional Academic Health Center-based clinics and endoscopy suites, the division offers ambulatory and procedural practices at Spring Mill, IU Health North hospital, and IU Health Saxony Hospital. Our endoscopy suite on the North side has been named after Dr. Douglas Rex, a world-renowned endoscopist and a pioneer in colorectal cancer screening. In continuing the tradition started nearly 30 years ago, the division has a robust outreach clinical program where faculty clinicians have established practices in the towns surrounding Indianapolis. Outreach programs are active in Tipton, Batesville, Zionsville, Martinsville, and Lebanon.
