Our research program is focused on understanding the key genetic, immunologic, and biochemical pathways that lead to the development of food allergy, eosinophilic esophagitis, and other related diseases, and how this information can be translated into therapeutic benefit. Our group uses a multifaceted approach using both human samples and mouse models to perform basic, translational, and clinical studies. Our current efforts are focused on investigating the environmental and immunologic factors that influence the development and severity of food allergy, identifying new approaches for the prevention and treatment of food allergy, and identifying single gene disorders associated with an increased propensity for food allergy and other allergic conditions.
