Research interests

Our lab works toward elucidating the ecological and evolutionary drivers of biological diversity on Earth. We borrow concepts and tools from community ecology and biogeography to try and gain a mechanistic understanding of the emergence, distribution and maintenance of diversity. To accomplish this, we conduct observational and experimental field studies and compile comprehensive databases on the distributions, ecological characteristics and evolutionary history of species.
