I am interested in many aspects of evolutionary biology, including phylogenetics, speciation, and social evolution. I have combined field observations and molecular techniques to address questions in a phylogenetic framework. I have used lizards and wasps as model organisms. I have worked on the phylogenetics and molecular evolution of these model organisms and more recently on the reproduction of social wasps, contrasting the biology and social structure of tropical vs. temperate species. The common element in these projects has been the use of molecular tools and a focus on molecular evolution.
