TEACHING AND RESEARCH AREAS

Research interest and emphasis focuses on the biogeography of southern dinosaurs, how dinosaur-dominated ecosystems differed from older and younger ecosystems, and the recognition of trends in the evolution of life on Earth that may occur on Earth-like planets elsewhere.
