The research mission of the Division of Gastroenterology is to advance the understanding, diagnosis, treatment and prevention of diseases of the digestive tract, liver and pancreas. Discoveries into the underlying mechanisms of gastrointestinal diseases and new treatment approaches are facilitated by a large research base within the MGH and the NIH-funded Center for the Study of Inflammatory Bowel Disease.

Dr. Ananthakrishnan
Dr. Ashwin Ananthakrishnan

My research focuses on understanding the epidemiology of inflammatory bowel diseases, identifying predictors of natural history of disease, and defining high-risk subgroups. The overarching goal of my research is to work towards improving our understanding of the pathogenesis of these diseases, and developing a personalized medicine approach to the management of IBD.

Dr. William Brugge

Dr. Brugge is an active clinical consultant in gastroenterology and gastrointestinal endoscopy, focusing on patients with complex pancreatic diseases. His research has focused on the early diagnosis of pancreatic cancer, developing a variety of endoscopic techniques to aspirate malignant and pre-malignant lesions of the pancreas, including cystadenomas, intra-ductal tumors, and masses, as well as the study of EUS guided techniques to ablate cystic pancreatic malignancies. He performs therapeutic endoscopic procedures such as ERCP, stent placement, FNA and EMR.
