Research Interests

The Baldridge Lab studies interactions of the intestinal commensal microbiota with viral (such as murine norovirus) and bacterial pathogens, and the regulation of these interactions by the mucosal innate immune system. The lab also explores viral evolution and phenotypic alterations in different immunological and anatomical contexts, using murine norovirus as a model.
