My research sits at the interface between macroecology and macroevolution, and aims to understand broad-scale patterns of biodiversity.

I use cutting-edge phylogenetic comparative methods, morphological data collected from museum specimens, phylogenies, ecological data, species geographic range maps, fossils, and various larger databases, to investigate a variety of questions including the influence of competition on macroevolutionary patterns, rates and modes of evolution, and convergent evolution. I work on a range of species, with recent projects on whales, snakes, chameleons, small mammals, dinosaurs, fishes, and birds.
