My primary research interest is the evolution of animal social behavior; however, my interests range from molecular evolution to sexual selection to phylogenetics. I also like to pursue both empirical and theoretical questions in my research. The organisms I have studied also comprise a diverse group, including fishes and primates. My recent work has included 1) the reconstruction of macaque phylogeny through analysis of mitochondrial DNA restriction-sites, 2) using DNA fingerprinting to assess the genetic structure of primate populations and determine paternity in wild populations, 3) phylogenetics and phylogeography of avian and fish taxa, and 4) development of new theory and methodology in phylogenetics and bioinformatics. My graduate students often combine molecular lab work with field work to better understand the evolution or ecology of a group of organisms, although I am also enthusiastic about advising students pursuing developments in evolutionary models and methodologies.
