Dr. DiMarino is the author of more than 100 original papers, and as a lead author his papers have appeared in the New England Journal of Medicine, Journal of Clinical Investigation, The American Journal of Physiology, Gastroenterology, The American Journal of Gastroenterology, and Gastrointestinal Endoscopy.

Dr. DiMarino is editor-in-chief, along with Stanley Benjamin, MD, Chief of Gastroenterology at Georgetown University, of Gastrointestinal Disease: An Endoscopic Approach, an original 2-volume textbook, which is currently in its second edition, published by SLACK Incorporated.

Dr. DiMarino is considered a preeminent consultative gastroenterologist. In May 2007, Dr. DiMarino received the American Gastroenterological Association 2007 Mentors Research Scholar Award, which is given to individuals "who have made enormous contributions to gastroenterology through mentoring." Dr. DiMarino's research interests have primarily been in the areas of esophageal, gastric, and small intestinal motility; celiac disease; and the safety of gastrointestinal endoscopy. At the request of the Food and Drug Administration, he authored the "White Paper," which is currently still in use as the standard for reprocessing endoscopic gastrointestinal instruments to protect patient safety between patient procedures.

Sidney Cohen, MD is Professor of Medicine and Director of the Gastrointestinal Research Program at Thomas Jefferson University in Philadelphia, Pennsylvania (2001 to present). Previously, Dr. Cohen served as chairman of the Department of Medicine at Temple University School of Medicine in Philadelphia (1986 to 2000).
