Ph.D. Ecology, University of California-Davis 2007
I am broadly interested in the ecology and evolution of plant and fungal communities. A major goal of my research is to understand the consequences of genetic variation and rapid evolution within species for the structure and functioning of diverse communities. I am particularly interested in the interactions between plants and soil microbial communities, especially mycorrhizal fungi, in determining competitive interactions between plants. To answer these questions, I use a combination of field, greenhouse, and molecular approaches. Most recently I have studied these processes in the context of exotic invasions, where I have found that rapid evolution in the chemical traits of a plant invader, combined with ecological and evolutionary changes in native plant and soil communities, may be acting to reduce the negative impacts of the invasion and allow the recovery of native communities. I will soon begin investigating the role of plant-fungal interactions in ecological responses to rapid climate change.
