My research focuses on how the interactions of mitochondrial and nuclear genes shape the evolution of eukaryotes. I am particularly interested in the role of mitonuclear interactions in the processes of sexual selection and speciation. For many years, carotenoid coloration has been a focused interest in my lab group, and we are currently studying the connections between the female mate choice, carotenoid metabolism, cellular respiration, and mitonuclear compatibility.
I teach Ornithology every spring and alternate teaching a graduate seminar on Mitonuclear Ecology and Sexual Selection.
