I am a mammalogist and a systematist. My research focuses on determining the evolutionary relationships of rodents and other small mammals and involves questions ranging from deep history to recent patterns in populations. I’ve worked on projects involving integrating genetic data with fossil information, using genetics to uncover how past climate influenced evolution, and developing and applying molecular evolution techniques. In addition to work in North America, my fieldwork with small mammals has taken me to West Africa (Guinea and Sierra Leone) and I’ve worked on species from Central Asia.
