Research

The St. Leger Lab uses entomopathogenic fungi as models for understanding how pathogens in general evolve different host ranges, respond to changing environments, invade hosts and counter host immune responses. The lab has also engineered hypervirulent insect pathogens expressing spider toxins. The potential of these engineered pathogens to control mosquito vectors of malaria is being tested in the field. Other interests include mutualistic associations between microbes and plants that can be exploited to benefit agriculture.
