- Distinguished Professor of Entomology and Chemical Ecology
Insect-to-insect or plant-to-insect chemical communication via olfaction, neuroethology, heliothine moth sex pheromone and host plant volatile mixture interactions, development of an insect antenna-based olfactory biosensor, discovery and development of novel insect attractants, traps and mating disruption dispensers, and evolution of sex pheromone blends.
- Professor Emeritus of Entomology
Structure and function of insect chemosensory systems, impact of sensory systems on chemically mediated behavior (especially feeding behavior of caterpillars), roles of key stimuli during the early phases of induced plant defenses, mechanisms of transduction in chemosensory cells, design of antifeedant chemicals, and development of new detectors.
- Distinguished Professor of Entomology
- Director, Center for Pollinator Research
- Professor of Entomology
Molecular mechanisms underlying differences in susceptibilities of insect species to the effects of synthetic or natural poisons, amino acid receptors as models for selective taste and insecticide action, cytochrome P450 monooxygenases and epoxide hydrolases as model detoxification enzymes degrading sensory chemicals at nerve receptor sites, peptide and protein taste receptors in beetles, development of novel biopesticides.
- Associate Professor of Entomology
- Extension Specialist
Chemically mediated tritrophic interactions, host-plant location by herbivores, host location by parasitoids, understanding how plants defend themselves against insect herbivores, including the release of volatile compounds as indirect defenses, phytohormone dynamics in response to herbivory, gall-inducing insects.
