I am broadly interested in early Mesozoic terrestrial vertebrate ecosystems, particularly during the Late Triassic Period (230-200 million years ago). My PhD research focuses on the origin and early diversification of dinosaurs. This study uses phylogenetic, biogeographic, and paleoecological perspectives to evaluate hypotheses for the early diversification of the dinosaurs. I am also involved in descriptive and systematic studies of other Late Triassic terrestrial vertebrates (such as phytosaurs, aetosaurs, and crocodylomorphs). Other research interests include marine vertebrate taphonomy and the use of strict apomorphy-based identifications of specimens in the fossil record.
