Our current research focuses on host-microbe interactions, and how it relates to intestinal inflammation. Specifically, we study the reciprocal interactions between commensal, pathobiontic and pathogenic microbes and innate lymphocytes such as natural killer T (NKT) cells and mucosa-associated invariant T (MAIT) cells.
