He served as Chief Medical Resident at Indiana University Hospital and joined the faculty at Indiana University in 1985. He received the Outstanding Teacher Award in the Introduction to Medicine course five times and has been awarded the Indiana University School of Medicine Outstanding Teacher Award as well as Department of Medicine’s Excellence in Teaching Award. He is a full-time clinical gastroenterologist at Indiana University Hospital. His major research interests have been in colorectal disease and, in particular, colorectal cancer screening and the technical performance of colonoscopy. He co-authored the colorectal cancer screening recommendations of the American College of Gastroenterology and the U.S. Multi-Society Task Force on Colorectal Cancer. He also authored the recommendations on quality in colonoscopy of the U.S. Multi-Society Task Force on Colorectal Cancer and the American College of Gastroenterology/American Society of Gastrointestinal Endoscopy. He has authored more than 250 original research papers, 60 book chapters, 220 invited papers, 60 editorials, and 40 guideline papers. He was an Associate Editor of Journal Watch Gastroenterology for 19 years and serves on the editorial boards of 11 gastroenterology journals. He is Editor-in-Chief of ASGE Journal Scan. He is the current chair of the U.S. Multi-Society (ACG, ASGE, AGA) Task Force on Colorectal Cancer.
