Research Focus

The focus of our lab revolves around understanding host pathogen interactions. Specifically we are interested in three separate but related questions:

1. How do intracellular pathogens parasitize their host cells?

2. How does the host recognize infection by intracellular pathogens?

3. How does recognition of intracellular pathogens by the innate immune system drive adaptive immune responses?
