Why are some groups of animals composed of many, varied species while others are not? As an evolutionary biologist I am interested in the macroevolutionary processes that generate the uneven distribution of diversity of lineages, morphology and ecology across the tree of life. I use phylogenetic comparative approaches to study the change in the diversification of morphology, function and ecology across remarkable radiations in vertebrates, with a special focus on fishes.
