Research Interests

The central goal of my research program is to understand the factors that govern the evolutionary dynamics of organismal diversification. How can we explain the uneven patterns of species richness and morphological diversity across the Tree of Life? Where is macroevolutionary theory adequate to explain diversity patterns and where must new models and methods be developed? Does morphological diversity always signal mechanical, functional, or ecological diversity? To address these questions, I work on two main systems: coral reef fishes and neotropical primates. My research approach is interdisciplinary and quantitative and crosses traditional boundaries among molecular phylogenetics, evolutionary morphology, and theoretical evolution. I construct evolutionary trees using phylogenomic approaches, test evolutionary hypotheses using phylogenetic statis- tical methods; use models of trait evolution to explore form-function dynamics identify and quantify organismal diversity using morphological and functional morphological techniques
