Research Interests

I use cutting-edge phylogenetic comparative methods of high-dimensional shape data to ask central questions about diversification mechanisms. My research focuses on factors that promote or constrain morphological and functional diversity, including (1) the drivers of diversification (e.g., intrinsic vs. extrinsic factors), (2) the influence of ecological interactions (e.g., diet type and feeding mode), and (3) the influence of functional constraints on form (e.g., morphological optimums). Most of my work concentrates on fishes; however, I am broadly interested in all animals, as evidenced by my postdoctoral work on arachnid evolution.
