Get to know Cynthia S. Haddad, MD
Dr. Haddad’s clinical interests include the diagnosis and management of pediatric food allergy and drug hypersensitivity, including evaluation of suspected drug reactions and strategies for safe drug allergy delabeling. Additional clinical interests include complex allergic and atopic diseases and emerging food allergy therapies, including oral immunotherapy and biologic agents.
Her research interests focus on food allergy and FPIES, including their underlying genetic mechanisms, natural history, risk factors, and clinical outcomes. She is also interested in improving the delivery of drug allergy care through research examining non-medical drivers of health and barriers to appropriate diagnosis and treatment, with the ultimate goal of improving access to equitable, evidence-based care for patients with allergic diseases.
