Research
Current research
My lab studies how bacterial pathogens interact with their host cells and with other microbes. I am particularly interested in (i) strategies used by pathogens to avoid destruction by host innate intracellular defenses, and (ii) mechanisms by which nonpathogenic probiotic bacteria can mitigate pathogen infection.
