Edit Profile

Research Narrative:

Ali Tavakkoli is a minimally invasive and bariatric surgeon at Brigham and Women’s Hospital and an Associate Professor of Surgery at Harvard Medical School. He is the co-director of the Center for Weight Management and Metabolic Surgery as well as the director of Minimally Invasive Surgery fellowship at the Brigham and Women’s Hospital. He received his medical degree from The London Hospital Medical College in England and became a Fellow of the Royal College of Surgeons of England (FRCS) before moving to Boston and finishing his surgical residency at the Brigham and Women’s Hospital and subsequently completing the Harvard Advanced Minimally Invasive fellowship in 2006. 

Dr. Tavakkoli leads an active NIH-funded research group that focuses on identifying novel approaches to modulate intestinal nutrient transport to treat obesity and diabetes.  He has received research grants from the Harvard Catalyst, Center for Integration of Medicine and Innovative Technology, as well as Harvard Nutrition Obesity Research Center. His current work is funded by the NIH and studies the mechanisms of diabetes resolution after gastric bypass surgery, focusing in the role of intestinal nutrient sensing.  His group's goals are to develop less invasive alternatives to surgery that can replicate the metabolic benefits of surgery without the risks.

He has a strong interest in surgical innovation and has created ITEAM (Innovative Technology and Engineering for Advancement of Medicine), a collaborative team of engineers, student, and physicians who focus on developing novel devices. He is an active member of many professional societies and an associate editor for the journal of "Digestive Disease and Sciences” and “Annals of Surgical Innovation and Research”
