he major focus of Dr. Williams’ research is the immunity and pathogenesis of human metapneumovirus (HMPV) and other respiratory viruses. His team established the epidemiology of HMPV as a leading cause of lower respiratory infection, identified integrins as receptors for HMPV, and discovered that HMPV enters cells through endocytosis. His group identified the HMPV F protein as the protective antigen and showed that F protein was an effective vaccine. Dr. Williams’ lab discovered that HMPV and other acute respiratory viruses induce lung CD8+ T cell impairment via the PD-1 signaling pathway, previously associated with chronic infections and cancer. His lab uses in vitro and mouse models to study the mechanisms by which HMPV interacts with and modulates the innate and adaptive immune systems. He is the author of >120 peer-reviewed research publications. He has directly mentored 7 graduate students (including 3 MSTP students); 6 MD fellows, 5 of who are in academic positions (4 physician-scientists, two with R01s); 4 medical students (one now a physician-scientist faculty); and two undergraduate students (both now in residency).
