About

We are part of the entomology department at the University of Kentucky in Lexington. Current research projects are focused on honey bee behavior and health, and wild bee agroecology, but past projects have used a number of different arthropod species, and the lab thrives on a broadly comparative scientific framework.

Big questions of interest:

  • How do social interactions “get under the skin” and cause behavioral change?
  • Why do some social experiences have lifelong impacts while others do not?
  • How do the brain and peripheral systems interact to regulate behavior?
  • What are the common evolutionarily principles of behavioral regulation?
  • How are behavioral and health traits connected?

Current projects:

  • The impacts of early-life environment on behavior and health
  • Neural, social, and ecological regulation of high-energy phenotypes
  • The molecular mechanisms that link behavior to health resilience
  • Floral landscape impacts on wild bee communities and honey bee health and behavior
  • The relationship between nutrition and honey bee viral load
