Overview


My research focuses on injury, repair, metaplasia, and cancer development in the gastrointestinal tract. My laboratory performs clinical and translational research with the goal of improving health of the gastrointestinal tract. Our work is based in observations from human clinical research. We use clinical data combined with data from patient samples to learn more about clinical risk factors for disease. Currently, we are working in Barrett's esophagus, H. pylori infection, autoimmune gastritis, gastric intestinal metplasia, as well as cancer prevention.  Our models include patient-derived organoids. We are particularly grateful to patients who partner with us in seeking new knowledge by enrolling in research protocols.
