Dr. J. Thomas Lamont received his medical degree in 1965 from the University of Rochester, and was intern, resident and chief resident in medicine at UCLA.

Following a GI Fellowship at Massachusetts General Hospital, he joined the faculty of Harvard Medical School in 1974. From 1980 to 1995, he was Chief of GI at Boston University School of Medicine, and from 1996 to 2012 was GI Division Chief at Beth Israel Deaconess Medical Center. He has served as Professor of Medicine at Harvard Medical School since 1996.

Dr. Lamont’s clinical interests are in the area of intestinal infections, particularly the management of C. diff infections. Thomas Lamont and his colleagues have made a number of important discoveries about C. diff infections, including how to diagnose C. diff in patients with inflammatory bowel disease, and how the immune system protects against this infection.

His group has published important papers on the C. diff carrier state, vaccine development and fecal transplant for recurrent C. diff. Dr. Lamont recently closed his research laboratory after 35 years of continuous NIH support including two separate research projects on intestinal mucin and C difficile toxins, as well as an NIH T32 training grant.

In addition to his clinical activities, Dr. Lamont serves as a mentor for young scientists and faculty members, and as a resource for manuscript, grant preparation, and career planning.

Dr. J. Thomas Lamont currently serves as Associate Editor for GI and Liver Diseases at the New England Journal of Medicine, and as Editor-in-Chief for Gastroenterology for UpToDate in Medicine.
