Research Interests

I am studying competition in the bacterium Vibrio fischeri, which uses a molecular syringe called the Type VI Secretion System(T6SS) to transfer toxic proteins into other bacterial cells in a contact dependent manner. In juvenile Hawaiian bobtail squids, Vibrio fischeri colonize within hours and different genotypes of Vibrio fischeri compete against each other for space inside the host. We are interested in knowing how certain host conditions turn on the T6SS during this colonization process. This work adds value when thinking about host-microbe interactions in the environment and the outcomes of T6SS dependent competition.
