Research Summary

Research interests include paleobotany, paleobiology and paleoclimatology. Research uses fossil plants to investigate ancient ecosystems, past environmental change, and the evolution and extinction of plants and plant-insect associations to emphasize questions with relevance for modern climate change, biodiversity, biogeography and ecological processes. Three specific areas of research include the end-Cretaceous (K-T) mass extinction and Eocene global warming, origins of South American plant diversity and the evolution of plant-insect associations.
