I have broad interests in evolution, particularly evolutionary ecology and evolutionary genetics. My students and I have carried out research on reproductive strategies and larval life history in frogs. We have also worked on the evolution of aposematism and mimicry. I am interested in molecular systematics and the use of phylogenetic trees to inform analyses of ecology and adaptation. Evolutionary ecology and phylogenetics are complimentary, because it is important to consider the effects of ecology on adaptation in a historical context. Similarly, phylogenetic information can be used to investigate the influence of ecological and social factors on adaptation in comparative analyses.
