Department of Entomology: My focus is on the behavior and chemical ecology of mutli-trophic interactions. This includes plant responses to belowground herbivory, nematode and insect community ecology, chemical ecology, and coevolution. Research projects include trophic cascades, above-belowground interactions, chemotaxis of soil nematodes, and the evolution of plant defense strategies.

Department of Entomology: I study the evolutionary development of complex social behaviors in bumblebees and fire ants using an integrative approach encompassing genomic, chemical and physiological tools. ​

Department of Entomology: We are seeking to understand rudimentary elements of insect olfaction involving signal acquisition and signal transduction using advanced imaging techniques such as atomic force microscopy in conjunction with neurophysiological recordings. We would like to get a better understanding of the evolution of olfaction in insects by using a comparative approach that involves moth species from several families, flies, and mosquitoes.

Department of Entomology: My research program uses molecular, proteomic and physiological approaches to investigate insect-plant interactions. My main interests are investigating the counter measures herbivores use in overcoming host plant defenses. Particular interest is on the role of herbivore salivary signals in suppressing the induced defenses of host plants.

Department of Plant Pathology: Molecular evolutionary genetics of fungi, molecular phylogenetics and systematics, identities and roles of fungal culprits in plant and animal diseases and toxicoses, curation of the world's largest collection of Fusarium cultures.

Department of Entomology: Bees are critical pollinators in natural and agricultural landscapes, and key model systems for the study of social behavior. My program seamlessly integrates research, education and outreach related to the biology, health and conservation of pollinators, particularly honey bees and bumble bees. My research uses integrative approach encompassing genomics, physiology, behavior, chemical ecology, and ecology. Our studies test and elaborate fundamental principles in animal behavior, evolutionary biology, disease ecology, and more recently landscape ecology. These studies have led to multiple new avenues of inquiry, and provided critical knowledge that can be deployed to improve conservation of pollinators and their ecosystem services.

Department of Entomology: I am interested in reducing the health risks to humans, as well as wild and domesticated animals, associated with arthropod vectors. Research in this area can be directly related to vector control, or focus on agricultural pests and food safety. Integrated research is necessary to develop novel control methods for vectors and agricultural pests as health risks increase from a growing population, climate change, and increased pesticide resistance.
