Research Interests:

My research aims to answer a fundamental question: how does the gut microbiota interact with host immunity in the context of gastrointestinal health and disease (e.g., inflammatory bowel disease (IBD), gastrointestinal infection, and colorectal cancer)? We are interested in the mechanisms by which certain pathogenic members of the commensal microbiota (so-called pathobionts) cause/exacerbate disease and the commensal beneficial microbiota works cooperatively with host immunity to combat pathogenic microorganisms within the gastrointestinal tract. We are also interested in the role of dietary factors in the regulation of competition between pathogenic and beneficial bacteria as well as the direct impact of dietary nutrients on host immunity.
