The focus of our research is to understand how chlamydiae evade innate host defense mechanisms, to define mechanisms of adaptive protective immunity, and to identify protective antigens. This information is being used to design new therapeutic strategies for the prevention of human chlamydial diseases. We use in vitro and in vivo models of infection together with comparative genomics, transcriptomics, proteomics, modern cell biology, and immunology to accomplish these goals.
Dr. Caldwell received his Ph.D. in pathobiology from the University of Washington in 1976. After completing a senior research fellowship in the Department of Medicine at the University of Washington in 1978, Dr. Caldwell joined the faculty of the University of California, San Francisco, as an assistant professor of microbiology and immunology. In 1980, he was recruited to the National Institutes of Health (NIH) as a tenure-track investigator in the Laboratory of Microbial Structure and Function. He became a tenured investigator in 1986 and chief of the Laboratory of Intracellular Parasites in 1990. He is a recipient of the NIH Director’s Award, NIH Merit Award, and PHS Superior Service Award. He was appointed to the NIH Senior Biomedical Research Service in 1997. Dr. Caldwell is a member of the editorial board of Infection and Immunity and a fellow of the American Academy of Microbiology. He is an internationally recognized leader in the fields of chlamydial pathogenesis and immunology.
