“Defining the gastrointestinal food allergic conditions in early infancy as the onset of atopic march”

Qian Yuan is co-director and principal investigator of the Food Allergy Center at Massachusetts General Hospital, a senior clinician of pediatric gastroenterology and Nutrition at Massachusetts General Hospital, and an associate professor of pediatrics at Harvard Medical School. He was appointed the inaugural incumbent of the Demarest Lloyd, Jr. Endowed Chair in Food Allergies in May 2023.

His research focuses on gastrointestinal food allergic conditions, including food protein induced allergic proctocolitis (FPIAP) in infancy, food protein induced enterocolitis syndrome (FPIES) in early childhood and eosinophilic esophagitis (EoE). In collaboration with FASI Investigator Dr. Wayne Shreffler, he has established a birth cohort (GMAP) in 2013 to longitudinally study the risk factors, clinical features and mechanisms of gastrointestinal food allergies in infants and children.
