Dr. Koelle's lab uses the power of modern immunologic methods and molecular sequencing to understand the immune response to infectious pathogens. We want to create better vaccines and understand how existing vaccines work. Diseases of interest include herpes simplex and varicella zoster virus infections, syphilis, and virally induced cancers such as Kaposi's sarcoma and Merkel cell carcinoma. Within the UW Dept of Global Health, the lab is most closely associated with the Pathobiology program.
