Characterization of the immune response to food allergens and the early stages of allergen-induced immune reaction

Wayne Shreffler is the director of the Food Allergy Center at Massachusetts General Hospital, the division chief of pediatric allergy and immunology at Mass General Hospital of Children, a principal investigator at the Center for Immunology and Inflammatory Diseases, and an associate professor of pediatrics at Harvard Medical School.

His research and multi-disciplinary clinical program focus on characterization of the immune response to food allergens and the early stages of allergen-induced immune reaction. In collaboration with Christopher Love at MIT, he conducts research for FASI focused on single cell profiling of T cells from peanut-allergic patients and individuals suffering from the allergic disease eosinophilic esophagitis.
