My lab focuses on the process of biological diversification, and we use varied approaches to understand how genes, organisms, and populations evolve. Understanding the evolution of mitochondrial genes, especially those coding for RNA, has been the emphasis of much of our work. Data from mitochondrial genomes has also allowed my lab group to help infer the systematic relationships among the chelicerates, one of the most species-rich groups of animals. At the population level, we examine factors that promote and inhibit speciation. including understanding the potentially adaptive role of visual signaling in different ecological settings.
