I am a Gastroenterologist at Mayo Clinic in Rochester, Minnesota. I have a broad interest in diseases of the pancreas, and my NIH-funded research focuses on the role of diabetes and hyperglycemia as a marker of undiagnosed pancreatic cancer. Additional areas of clinical research involve understanding the clinical spectrum of autoimmune pancreatitis, and I am also interested in cystic tumors of the pancreas, including their classification, prevalence and natural history.

I serve on the editorial board for Pancreas and also Pancreatology, the journal of the International Association of Pancreatology. I have been selected to serve as editor-in-chief of Pancreatology for a three-year term beginning in 2019.

I have served as President of the American Pancreatic Association and the International Association
of Pancreatology and as chair of the National Pancreas Foundation Grant Study Section. I currently serve on the Scientific Advisory Boards of the Hirshberg Foundation for Pancreatic Cancer Research, the Kenner
Family Research Fund, and Stand Up to Cancer.
I have received the Department of Internal Medicine Outstanding Mentor Award, the Lifetime Achievement Award (2016) from the Collaborative Alliance for Pancreatic Education and Research, the Mayo Clinic Distinguished Clinician Award (2017), and the American Gastroenterological Association Institute Council Research Mentor Award (2018)
