Area of Interest

My research focuses on the evolutionary history of small mammals in the Old World, and in particular, the island archipelagos of Southeast Asia.  In general, I combine biodiversity inventories with molecular and morphological systematics to understand how organisms diversify and fill the environment. I am especially interested in the effects of ecological opportunity, time of colonization, and incumbency on the tempo and mode of speciation in island-dwelling lineages.  Additional details are provided on my lab web-site.
