• 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.
