Research Overview

Dr. Bousvaros studies the pathogenesis and therapy of inflammatory bowel disease (IBD). Goals of Dr. Bousvaros's research include the identification of microbial pathogens that may trigger exacerbations of Crohn's disease or ulcerative colitis and the evaluation of probiotic therapies in the treatment of IBD. 

About the Researcher

Dr. Bousvaros received an MD from Duke University and an MPH from the Harvard School of Public Health. He completed fellowships at Children's Hospital Boston and Massachusetts General Hospital.
