I work on the evolution of species diversity. Why does life evolve into the distinct and diverse entities we call species? Why do some lineages and regions contain more species than others? What are the adaptive causes and consequences of species diversity? The work combines theory with field, experimental and molecular approaches to explore these fundamental questions in plant, animal and microbial systems. I welcome enquiries from students or post-docs interested in working in this general field. For more information on our lab, visit our lab website here.
