My research interests are broad, and I have published papers in ecology, taxonomy, medical entomology, and genetics, including such taxa as frogs, bats, crickets, mosquitoes and mites.  My research has focused primarily on the population dynamics, genetics, and evolutionary biology of insects that affect the health of humans and other animals.  I am currently investigating the genetic differentiation and ecology of malaria mosquitoes in Bolivia under a grant from the National Institutes of Health.  Another aspect of my research program examines sociobiological questions in yellowjackets and fire ants.   For example, my students and I recently completed two studies that examine genetic relatedness and reproduction in yellowjacket nests with single or multiple queens.
