Anthony J. Lembo

Anthony J. Lembo serves as Associate Professor of Medicine at Harvard Medical School and Director of the GI Motility Laboratory within the Department of Medicine, Division of Gastroenterology at Beth Israel Deaconess Medical Center (BIDMC) in Boston, Massachusetts.

His academic background includes:

• Undergraduate degree in Mathematics from Amherst College
• Medical degree from Tufts Medical School
• Internal medicine internship/residency and gastroenterology fellowship at UCLA Medical Center

Dr. Lembo's research program centers on functional gastrointestinal disorders, with primary focus on irritable bowel syndrome (IBS), chronic constipation, and dyspepsia. He has pioneered investigations into the neurobiological mechanisms of placebo effects in gastrointestinal conditions, demonstrating how psychological and contextual factors modulate symptom perception and treatment response in functional bowel disorders. His work bridges clinical gastroenterology with psychosomatic medicine, emphasizing brain-gut axis interactions.

As Director of BIDMC's GI Motility Laboratory, he oversees advanced diagnostic testing for esophageal, gastric, and colonic motility disorders using high-resolution manometry, impedance planimetry, and wireless motility capsule technologies. The laboratory serves as a hub for both clinical diagnostics and translational research in gastrointestinal neuromuscular function.

Dr. Lembo began his academic career at UCLA Medical Center as Clinical Instructor of Medicine and Co-Director of the Functional Bowel Disorders and GI Motility Center before joining Beth Israel Deaconess Medical Center's faculty in 1997, where he has maintained continuous academic and clinical leadership in gastroenterology.
