My research in the area of phylogenetic systematics has involved using DNA sequence data to improve our understanding of the evolutionary relationships of organisms. Phylogenetic hypotheses provide a framework to address questions as diverse as species delineation, biogeography, and character evolution.
Past research projects on the Centrarchidae and the Petromyzontiformes have been sponsored by the National Science Foundation. Topics of more recent research includes freshwater shrimps in the family Atyidae and freshwater mussels in the genus Ptychobranchus.
