The Collegium Internationale Allergologicum (CIA) is a prestigious international organization dedicated to the advancement of research, education, and collaboration in the field of allergy and immunology. Founded in 1954, the CIA brings together leading experts, researchers, and clinicians from around the world to exchange knowledge, promote best practices, and foster innovation in the diagnosis, treatment, and understanding of allergic and immunologic diseases. Through its meetings, publications, and initiatives, the CIA plays a vital role in shaping the future of allergic and immunologic disease research, aiming to improve the lives of patients worldwide.
Welcome to the Collegium Internationale Allergologicum (CIA)
From its inception in 1954, the CIA was envisioned as a society that would promote and celebrate excellence in basic science and clinical investigation in allergy and related fields.
Dr. Rothenberg is based at Cincinnati Children’s Hospital Medical Center, where his research focuses on the mechanisms of allergic inflammation, eosinophilic gastrointestinal diseases, and allergen-mRNA vaccination. His work has led to multiple first-in-field discoveries and therapies in EoE and allergic disease, including advances in anti-IL-5, IL-13, and TSLP pathways, molecular diagnostics, genetic susceptibility, barrier dysfunction, and novel vaccine and biomarker platforms.
The Collegium Internationale Allergologicum gratefully acknowledges the following companies for their support and membership on the CIA Corporate Advisory Council.
