Elise Liu

Elise Liu, MD, PhD, is an Instructor of Medicine in the Department of Internal Medicine at Yale School of Medicine, specializing in Allergy and Immunology. She is a member of the Janeway Society and actively contributes to research and clinical care in food allergy and mucosal immunology.

• Instructor of Medicine, Yale School of Medicine
• Department: Internal Medicine, Section of Allergy & Immunology
• Research Focus: Gut immunoglobulin A, food allergy mechanisms, oral tolerance
• Professional Affiliations: American Academy of Allergy, Asthma & Immunology (AAAAI), American Society for Clinical Investigation (ASCI)

Dr. Liu's research centers on understanding the role of immunoglobulin A (IgA) in the gut and its implications for food allergy development and tolerance. Her work combines clinical insights with experimental models to uncover immune mechanisms underlying allergic responses, particularly to peanut and egg. She investigates how dietary factors, such as food matrix composition, influence allergenicity and how metabolic pathways regulate IgA+ plasma cells. Her research has significant translational potential for developing diagnostics and therapies for food allergy.

Her recent publications span high-impact journals such as Science Translational Medicine, Journal of Allergy and Clinical Immunology, and Mucosal Immunology. Themes across her work include the search for biomarkers of natural tolerance, the impact of gut permeability on anaphylaxis, and emerging diagnostic tools in allergy. Her research frequently involves collaborations with leading immunologists such as Dr. Stephanie Eisenbarth.

Dr. Liu has received several prestigious awards, including:

• AAAI Foundation Faculty Development Award (2024)
• Emerging-Generation Award (2023)
• Membership in the American Society for Clinical Investigation (ASCI)

She is also involved in professional service, serving on the Traditional Medicine Residency Intern Selection Committee at Yale. Dr. Liu mentors trainees and contributes to advancing physician-scientist development through her participation in the Janeway Society. While no formal advisees are listed, her role as an instructor and researcher positions her as a key figure in training future allergists and immunologists. Her laboratory work is conducted within the broader ecosystem of Yale’s immunology and translational research infrastructure.
