Research Summary

In my laboratory we combine cellular and molecular approaches to dissect T cell mediated resistance to pathogens. Specifically, we use murine infection with Listeria monocytogenes, a bacterial pathogen or lymphocytic choriomeningitis virus, as model systems to understand the biology of CD8+ T cell mediated immunity to infection. We are also studying the factors that determine CD8 T cell mediated immunity against liver-stage malaria infection. Current projects involve:

1. Regulation of memory T cell development

2. Effector mechanisms of CD8 T cells in whole animal models of infectious disease

3. T cell homeostasis in response to infection

4. T cell mediated immunopathology after virus infection

5. CD8 T cell immunity against liver-stage malaria
