My current research interests stem from my desire to understand fundamental aspects of biological diversity. These fundamental aspects include the relationships of organisms and their morphological complexity. I study these aspects using phylogenetic systematics, geometric morphometrics and other tools. These tools allow us to understand broader themes such as historical biogeography, molecular evolution, conservation and the evolution of morphological diversity. As an ichthyologist my focus is on process oriented evolutionary biology in marine fishes and pattern oriented evolutionary biology in freshwater fishes. As a systematist I use molecular and morphological tools to help discover relationships among species and resolve taxonomy in order to better understand the evolutionary history of fishes.
