I am interested in the patterns and processes that underlie adaptive diversification in the most diverse group of vertebrates—fishes. I test hypotheses regarding adaptive radiation, the evolution of diet, and the impact of traits considered key innovations (such as pharyngeal jaws, stomachs, etc.) on ecological and lineage diversification. I address research questions with a variety of approaches, including phylogenetic comparative methods, micro-computed tomography (microCT), genomics, field work, construction of large ecological databases, and high-speed videography.
