Adaptive radiation

Adaptive radiations may play key role in the diversification of life on Earth. We are interested in both the causes and consequences of adaptive radiation. Much of this work involves island lizards.

Comparative Methods

We are developing new comparative approaches to answer ecological and evolutionary questions about the tempo and mode of diversification.

Species interactions

We are developing and applying methods to search for the signature of species interactions in comparative data. This includes analyses of network evolution, trait evolution, and species abundances in a phylogenetic comparative framework.

Diversification in microbial biofilms

A new project in the lab seeks to use new phylogenetic comparative methods to study diversification in microbial biofilms. Evolutionary diversification in biofilms has important medical consequences; we seek to test hypotheses about this diversification using a variety of statistical models.
