Our lab works on the T cell immune response to a variety of human pathogens. Currently funded projects include Treponema pallidum (syphilis), herpes simplex virus types 1 and 2, varicella zoster virus (the cause of chicken pox and shingles), SARS-CoV-2, and Merkel cell polyoma virus (MCPyV, the cause of a viral skin cancer). We are fortunate to work with translational scientists including animal models and analysis of human specimens from vaccine clinical trials. David also does clinical work in Infectious Diseases at Harborview Medical Center,a component of UW Medicine.
