Matthew Memoli

Matthew J. Memoli is an American physician-scientist and infectious disease researcher who had served as the acting director of the National Institutes of Health (NIH). He was the director of the Laboratory of Infectious Diseases (LID) Clinical Studies Unit in the National Institute of Allergy and Infectious Diseases (NIAID).

Education Matthew J. Memoli graduated from the College of William & Mary with an undergraduate degree. He earned a M.S. in microbiology from Thomas Jefferson University in 1998. Memoli participated in an ethics debate on vaccine mandates hosted by the NIH in December 2021. During his direction in early 2025, the NIH suffered from confusion regarding details of purchasing and conducting research. On February 7, 2025 his office issued a notice on capping the indirect cost rate at 15%. For some universities this corresponds to more than a 75% decrease from the current rate. Several states have subsequently sued the NIH, arguing that "Without relief from NIH’s action, these institutions’ cutting-edge work to cure and treat human disease will grind to a halt."
