Coevolution, mutualism, evolution of plant-insect interactions.

Understanding biodiversity requires more than identifying the number of species on earth. We must also elucidate how species interactions govern the dynamics of communities, ecosystems, and species diversity. My lab uses a broad combination of approaches including experimental ecology, field observations, molecular phylogenetics, and population genetics to understand the role that interspecific interactions play in creating diversity.
