Dr. Davis is the Burt and Marion Avery Family Professor of Immunology; Director of the Institute for Immunity, Transplantation, and Infection; and Chair of the Department of Microbiology & Immunology at Stanford University School of Medicine. He is an Investigator with the Howard Hughes Medical Institute. His research focuses on how T and B lymphocytes recognize specific antigens. This interest includes the structural and biochemical underpinnings of T cell receptor binding and signal transduction and the dynamics of molecular movement at the T cell/antigen-presenting cell interface. He is also interested in the unique challenges of (and solutions to) studying the human immune system, particularly in the context of infectious diseases and vaccination strategies.
