I practice and publish within a fairly narrow clinical domain - gastroenterology - however, I am always invoking 'bigger questions' through this smaller lens. I am very interested in modeling, decision-analysis, cost-effectiveness analysis, and - in general - outcomes research. I am also interested in the shared decision making process, both as a clinical practice and an area of research.
