  • Ryan Doster, M.D.

    Ryan Doster, M.D.

    Instructor in Medicine
    Division of:
    Infectious Diseases
    Previous Institution:
    Vanderbilt University Medical Center
    Previous Role/Title:
    Fellow, Division of Infectious Diseases
    Specialty:
    Infectious Diseases
    Education/Training:
    M.D. - Indiana University School of Medicine
    Hometown:
    Churubusco, IN
    Interests/Achievements:

    The goal of Dr. Doster’s research is to understand mechanisms by which bacteria like GBS are able to establish vaginal colonization and then ascend to cause invasive disease during pregnancy (chorioamnionitis). Bacterial infections during pregnancy lead to adverse outcomes including stillbirth, preterm birth, neonatal sepsis, and meningitis. Streptococcus agalactiae, also known as Group B Streptococcus (GBS) is a Gram-positive bacterium that colonizes up to 50% of pregnant women. Vaginal GBS carriage is a major risk factor for chorioamnionitis and neonatal sepsis. Dr. Doster is particularly interested in the role of bacterial biofilm to promote vaginal colonization, which may increase potential for bacterial invasion, as well as how GBS interacts with and alters host-immune responses. Host inflammatory responses to infection including release of cytokines and metalloproteinases that contribute to preterm birth pathogenesis. By understanding these pathways, Dr. Doster hopes to identify new, actionable targets to prevent adverse outcomes during pregnancy. He utilizes multiple methodologies to understand microbial-host interactions during pregnancy, including high-resolution microscopy techniques, animal models of pregnancy infection, and human tissue chorioamnionitis models.

She has not decided what her future research interests will be, but she believes that her specialized interests will develop over time as she grows in practice. She acknowledges that it will take a considerable amount of time to transition from being a novice to an expert, but when she reaches that level in the future, Sherlyn looks forward to precepting new APRNs/Pas and would like to do lectures on topics related to her specialty.
