Raymond St. Leger

Raymond J. St. Leger is a mycologist who is currently a professor of entomology at the University of Maryland, College Park who specializes in entomopathogenic fungus, or fungi that act as parasites of insects. Other interests include fungal behavior and evolution, fungal toxins, molecular biology of fungi, and insect control with fungi.
