Research at Mass General
The group is part of the Mucosal Immunology and Biology Research Center within the Division of Pediatric Gastroenterology, and is also affiliated with the Massachusetts General Hospital Center for the Study of Inflammatory Bowel Disease.
The main interest of our group is in clarifying how host and environmental factors influence the early phases of the immune response to bacteria that reside within or infect via the gastrointestinal tract.
Current projects include investigations of the following:
