Research Focus

Clinical outcomes research in inflammatory bowel disease. Specifically, interested in vaccine-preventable illnesses, disease phenotype/classification, post-operative outcomes, disease activity assessment, and health-related quality of life.

Research Contributions

Discovered that commonly prescribed immunosuppressive medications impair normal vaccine responses in inflammatory bowel disease. Described that the presenting disease phenotype may influence the natural history or postoperative outcomes of ulcerative colitis. Simplified disease activity and quality of life assessments for Crohn's disease.

Current investigations include:

Ongoing assessments of predictors of post-operative outcomes. Clinical studies to determine optimization of vaccine responses among immunosuppressed patients.
