Ph.D. 1990 University of London
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
- Manipulating arthropod communities in turfgrass ecosystems through fungal endosymbionts and entomopathogenic nematodes,
- Developing new strategies to utilize entomopathogenic nematodes in vegetables, grapes, nurseries, and landscapes,
- Developing molluscicidal nematodes for slug control,
- Genome sequence of the entomopathogenic nematode, Heterorhabditis bacteriophora
- Molecular, genetic, and physiological approaches to extend longevity and stress tolerance in entomopathogenic nematodes, and
- Nematode communities as soil health indicators
