Research Interests

My research focuses on understanding macroevolutionary dynamics in fishes, using applied methods in statistical phylogenetics and phylogenomics. Major questions concern how freshwater fish clades have diversified during their evolutionary history and how morphological disparity can be used to explain ecological diversity. I am also interested in analytical methodologies for estimating tempo of diversification and phylogenetic inference using large-scale datasets. My major taxonomic focus is on the Neotropical and Paleotropical fishes of the order Characiformes, which includes the popular tetras, piranhas, and allies, but I am also open to expand my research to other fish groups.
