About the expert

Focus: Cutting-edge immunology research on the biological mechanisms of Long COVID and other post-acute infectious syndromes

Sterling Professor of Immunobiology at Yale School of Medicine and founder of the new Yale Center for Infection and Immunity (CII). One of the world's leading immunologists working on post-acute infectious syndromes including Long COVID and ME/CFS. Her lab investigates four primary mechanism hypotheses for Long COVID: persistent viral infection, autoimmunity, latent virus reactivation, and tissue-wide inflammatory dysregulation. Notable work includes biomarker research reporting 94% accuracy for Long COVID detection from blood markers even when standard tests appear normal. Mainstream academic immunology credentials at the highest tier; HHMI Investigator; member of the National Academy of Sciences. Patient-led community research partnerships shape her approach.

Iwasaki: The biological mechanisms behind Long COVID
Long COVID may have four leading causes: leftover virus, autoimmunity, latent virus reactivation, or persistent inflammation. Yale researchers have reported promising biomarker patterns in research settings, but these need further validation. Current immunology research supports a biological basis even when standard tests appear normal.
