Research Abstract

Our overall mission is to advance epidemiologic investigation for the translation of discoveries into effective clinical interventions. We currently focus on chronic digestive diseases, including gastrointestinal cancer (colorectal, esophageal, pancreatic), inflammatory bowel disease, diverticulitis, and gastrointestinal bleeding. We utilize molecular approaches encompassing genetic, metabolomic, proteomic, and biochemical platforms applied to populations ranging from large cohort studies to small biomarker-driven clinical trials. We also have a major effort in investigating the oral and gut microbiome as a determinant and mediator of chronic disease.
