My research program centers on the use of DNA sequence data for inferring the evolutionary history among organisms. My primary research focus is on the cospeciation and coevolution of parasitic mites and their bird hosts. As part of this project my lab is particularly interested in passerine bird phylogeny. Consequently, the lab has been sequencing a number of nuclear and mitochondrial genes in a variety of parasitic mite and bird taxa. Other systematic projects in my lab include the molecular phylogeny of Drosophila, dragonflies and damselflies, land snails, centipedes, scorpions, spiders, and small mammals (chipmunks and ground squirrels).
