The Xavier Laboratory at the Massachusetts General Hospital and Broad Institute focuses on systematic characterization of genetic variants to understand the regulation of barrier defense, innate and adaptive immunity; chemical biology to control cellular disease phenotypes suggested by human genetics; molecular functions of the microbiome to determine impacts on health and disease; and development of prediction algorithms to identify immunodominant antigens that drive pathogenic and homeostatic T cell responses.
