Habitat associations and host plant relations of grasshoppers
Development of management practices for grasshoppers
Insect ecology, especially insect-plant relationships Insect pest management, especially feeding deterrents, biological control, damage assessment, and economic thresholds
Current research projects: ecology of redbay ambrosia beetle, vector of laurel wilt; chemical management of grasshoppers; ecology of carrion-feeding flies; identification and ecology of agriculturally important terrestrial molluscs (slugs and snails); importance of insects in the ecology of vertebrate wildlife
