Research
My laboratory studies molecular mechanisms of virulence of the food-borne pathogen Listeria monocytogenes. One ongoing project focuses on understanding the process by which Listeria induces its internalization into host human cells. Another project examines how Listeria spreads from infected human cells to surrounding healthy cells.Publications
