Research Detailed:

Evolutionary morphology and systematics are the focus of my research. In particular, I am interested in the large-scale phenomena that have shaped the evolution and diversification of vertebrates in both space and time. I primarily utilize two study systems: 1) Triassic–Jurassic dinosaurs and 2) Cenozoic and living waterbirds, to test evolutionary patterns of character evolution, biogeography, ecology, and diversification in a phylogenetic framework. An additional area of study includes systematic research on fossil and living scleractinian corals. 

EVOLUTION OF TRIASSIC/JURASSIC DINOSAURS The origin and early diversification of dinosaurs represent the most poorly known events of Mesozoic dinosaur evolution. My field research in the western USA and Antarctica fills major geographic, temporal, and taxonomic gaps in vertebrate evolution, and includes descriptive and alpha-taxonomic studies. Primary research questions include: 1) How are vertebrate phylogeny, diversification, and biogeography affected by mass extinction events? and 2) Are patterns of faunal change observed in the fossil record due to local, regional, or global processes? 

CENOZOIC WATERBIRD EVOLUTION AND SYSTEMATICS My research on avian evolution focuses on evaluating conflict and congruence between morphological and molecular datasets, incorporating fossil data to test patterns of temporal diversification and character evolution, and using an integrative approach to understand the evolution of complex morphological character systems and novel body plans. I use the avian order Pelecaniformes, and the larger waterbird group (e.g., penguins, storks, herons), as my study system. Major questions include: 1) Do disparate types of data agree on patterns of vertebrate phylogeny, and if not, why do they differ? and 2) How have complex morphological character systems (e.g., skeletal pneumaticity, flightlessness, wing-propelled diving) evolved? 

PHYLOGENETIC COMPARATIVE METHODS IN PALEONTOLOGY My development and application of phylogenetic comparative methods to questions in paleobiology stem from a desire to deal with real-world issues of the fossil record. These include uneven and incomplete geographic sampling of faunas, uncertainty of stratigraphic ranges of fossil taxa, and working with multiple competing hypotheses of phylogenetic relationships. Primary research questions include: 1) How does the temporal and spatial heterogeneity of the fossil record affect phylogenetic and biogeographic inference? and 2) How can modern phylogenetic comparative methods be utilized to test paleobiological hypotheses, and what unique challenges do fossil data pose for these methods?
