    Clinical Associate Professor, Medicine - Gastroenterology & Hepatology

    BioThe management of inflammatory bowel disease continues to evolve, with the introduction of biologic and small molecule therapies and new goals of treatment, with an emphasis on healing the bowel. My career goal since my graduation from IBD fellowship in 2012 has been to improve the outcomes and quality of life of patients with inflammatory bowel disease. In line with these goals, my research has focused investigating new noninvasive diagnostic test, finding factors early in the disease course that might predict a more aggressive disease course and need for different therapies, and investigating new promising effective medications with less side effects.
