Dr. Raymond Johnson

Biography

Raymond Johnson is an Associate Professor at Yale School of Medicine in the Department of Medicine, specializing in Infectious Diseases. He received his M.D. and Ph.D. from the University of Chicago, completing his Ph.D. in Molecular Genetics and Cell Biology, focusing on the pathogenesis of Herpes simplex virus. He underwent medical residency and Infectious Diseases training at Washington University in St. Louis, where he also participated as a Howard Hughes Research Fellow. Since joining the faculty at Indiana University in 2001, he has focused on Chlamydia pathogenesis. His laboratory's primary goal is to understand protective immunity against Chlamydia infections in the reproductive tract to facilitate vaccine development. Dr. Johnson's research includes exploring T cell interactions with infected epithelial cells, utilizing T cell cloning techniques to gain deeper insights into mucosal T cell immunobiology. His work has identified IL-13 as a central player in Chlamydia immunobiology and is currently focused on the role of chlamydia-specific CD4 and CD8 T cells in preventing immunopathology during C. muridarum genital tract infections. In addition to his research, he treats patients with complex infectious conditions, ensuring they understand their diagnoses and treatment options.
