Research in my lab uses genetics and genomics to explore the processes of speciation, extinction, diversification, and biogeography which have shaped the tree of life from its origin to the present. We are especially interested in how the global environment has impacted the evolution of life through continental drift, sea level variation, and climatic change, as well as the impact of deforestation on current species. We often use time-calibrated phylogenies (timetrees) to address these questions. Most of my current "global" analyses bring data together in new ways, involving bioinformatics for data analysis.
