I study how changes in the physical environment (such as climate change and mountain building) contribute to the evolution of mammal species and faunas at varying temporal and geographic scales. Field aspects of the work include collecting fossils from long stratigraphic sequences that can be well-dated by biostratigraphic, paleomagnetic, or radioisotopic techniques. Lab analyses utilize database and GIS systems to identify faunal changes through space and time; the faunal patterns are then compared with independently identified changes in the physical environment to test various evolutionary and biogeographic predictions.
