The evolution of sociality represented one of the major transition points in the history of life. We are interested in understanding how evolutionary processes affect social systems and how sociality, in turn, affects the course of evolution. The principal subjects of our research are the social insects (ants, termites, bees, and wasps). We take an integrative approach to studying social systems. For example, we make use of a variety of techniques, including computer simulations, analytical theory, behavioral experiments, and field studies, as well as molecular genetic and genomic analysis. Our research primarily focuses on understanding the social structure and mating biology of invasive social insects. In addition, we study the process of development in the context of sociality.
