Research Interests

My research examines the evolutionary biology of complex systems with a heavy emphasis on ant societies. Ants are well-suited model systems because their societies range from small aggregations of distantly related individuals to colonies composed of perfect clones. Moreover, the dominance of ants in low to mid latitudes was undoubtedly facilitated by the symbioses ants form with bacteria and fungi.

Themes of my research include behavioral genetics, population genetics, mating systems, chemical ecology and communication, microbial ecology, disease management and the evolutionary biology of microbial symbioses.

Much of my recent research has investigated evolutionary genetics and intergenomic epistasis of range expansion of mutualisms. Important collaborators on these topics are Timothy Linksvayer (evolutionary genetics) at the University of Pennsylvania and Ulrich Mueller (intergenomic epistasis) at the University of Texas at Austin. With the latter I currently have an active collaborative NSF grant (DEB – 1354629). Other sources of funding include the Texas Museum of Natural Science.
