Cheryl Day, PhD

Project 1 Co-Director

Assistant Professor

Department of Microbiology & Immunology, Emory University School of Medicine


Dr. Day received her PhD in Virology from Harvard University in 2003. She was awarded a post-doctoral fellowship from the Royal Society in the United Kingdom to pursue research at the University of Oxford investigating the phenotype and function of HIV-specific CD8 T cells. She then transitioned to Durban, South Africa, and expanded her cellular HIV immunology studies to include HIV/TB co-infection. She subsequently joined the faculty of the University of Cape Town to pursue research on T cell immunology in individuals with latent Mycobacterium tuberculosis infection and active TB disease. Dr. Day is currently an Assistant Professor in the Department of Microbiology and Immunology in the Emory University School of Medicine, and a faculty member in the Emory Vaccine Center. The research in her laboratory focuses on investigating the relationship between mycobacterial antigen load and M. tuberculosis-specific T cell functional capacity, determining the effect of immune regulatory molecule expression on M. tuberculosis-specific T cell function and phenotype, and understanding the mechanisms of cross-talk between NK cells and antigen-specific T cells in the context of HIV/TB co-infection.
