As a community ecologist, I am interested in the factors that allow species to coexist. I am interested in how evolution on contemporary time scales alters the outcome of species interactions and affects species and genetic diversity in communities. However, species in natural communities interact with many other species, so evolutionary outcomes are the result of multiple direct and indirect species interactions. Consequently, I also examine the evolutionary importance of indirect species interactions to better understand how species evolve in a community context.
My research combines theoretical and experimental approaches that bridge the gap between evolutionary biology and community ecology. I have explored these questions in various natural systems, including plant-herbivore interactions in California grasslands, microbial communities that live inside pitcher plants, coral-algal symbioses, and communities of epifaunal marine invertebrates.
