My research interests encompass ecosystem level approaches to pest management with current emphasis on the interactions among trophic levels in turfgrass. Much the work in my laboratory is focussed on microbial control of arthropods with fungal endosymbionts of grasses, entomopathogenic and molluscicidal nematodes. Specific projects include

1. Manipulating arthropod communities in turfgrass ecosystems through fungal endosymbionts and entomopathogenic nematodes,
2. developing strategies to utilize entomopathogenic nematodes in vegetables, grapes, nurseries, and landscapes,
3. developing molluscicidal nematodes for slug control,
4. molecular, genetic, and physiological approaches to extend longevity and stress tolerance in entomopathogenic nematodes, and
5. microarthropod and nematode communities as soil health indicators
