Intérêts de recherche

I am interested in gastrointestinal and hepatobiliary immunology, microbiology and endocrinology. I study the molecular mechanisms of gut-liver communication in the homeostasis and immunity of the enterohepatic system, with an emphasis in the role of commensal and pathogenic bacteria in these fundamental processes.
