The Maintenance of Biological Diversity

We study the processes that enable species to persist through time, which are those responsible for the maintenance of biological diversity. Specifically, we investigate how historical, evolutionary and ecological process interact to govern community assembly and species coexistence. We pay particular attention to those processes that shape the structure of species pools, and how they trickle down to influence the structure of local communities.
