My research interests include phylogenetics, modeling biological data, statistical analysis of molecular data, and parallel computing. I am particularly interested in reconstructing species phylogenies from multilocus sequences., I and my colleagues have developed several phylogenetic methods for estimating the evolutionary history of species.
