Research Overview

The focus of my research is on fish diversity and evolution. I study the systematics (taxonomy and classification) of fishes using a combination of morphology- and gene-based lines of evidence. The goal of this work is to produce accurate and precise information on the nature and geographic distribution of fish biological diversity. In turn, this knowledge provides the foundation for examining other characteristics of evolution (e.g., molecular evolution, timing of diversification and colonization, etc).
