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.
