Dr. Douek was appointed to the NIH Vaccine Research Center in November 2000. His laboratory, the Human Immunology Section, studies the processes that determine the course of human diseases in which the immune system, particularly its T cell arm, plays a central role in their pathogenesis and outcome. He aims to use the knowledge gained to initiate clinical studies of new therapeutic and vaccine approaches.
