John V. Williams, MD
- Division Director, Infectious Diseases, Professor of Pediatrics and Microbiology & Molecular Genetics, and Director, Institute for Infection, Inflammation, and Immunity in Children (i4Kids)
Administrative Assistant: Kathy Kotova
John V. Williams, MD, is Professor of Pediatrics, Microbiology & Molecular Genetics; Henry L. Hillman Professor of Pediatric Immunology; Chief, Division of Infectious Diseases; and Director, Institute for Infection, Inflammation, and Immunity in Children (i4Kids). Dr. Williams is an international authority on the epidemiology, immunity, and pathogenesis of respiratory viruses. The major focus of his research is the immunity and pathogenesis of human metapneumovirus (HMPV). His team described the epidemiology of HMPV, a leading cause of lower respiratory infection, and discovered that HMPV uses integrins as receptors to enter cells through endocytosis. His group discovered that HMPV and other respiratory viruses induce lung CD8+ T cell impairment via PD-1 signaling. Dr. Williams also leads CDC-funded surveillance studies of acute respiratory and gastrointestinal infections in children based at Children’s Hospital of Pittsburgh. He conducts collaborative research with clinical investigators at the University of Pittsburgh and international sites. He has participated in studies of respiratory virus epidemiology in North America, South America, the Middle East, and Africa. His group has published studies on coronaviruses, influenza virus, HMPV, parainfluenza viruses, respiratory syncytial virus, and rhinoviruses.
He completed his undergraduate education at Northern Virginia Community College and the University of Virginia and attended medical school at the Medical College of Virginia/Virginia Commonwealth University. He trained in pediatrics at Children’s Hospital of Pittsburgh/University of Pittsburgh and completed fellowship in Pediatric Infectious Diseases at Vanderbilt University Medical Center.
