I am fascinated by symbioses. I am interested in unraveling how symbiotic interactions influence community processes, and how they evolve in general. The topics I study are at the forefront of community and evolutionary ecology, including: interactions governing community diversity, diversity in mutualistic interactions, network connectivity in plant communities, and the evolutionary history of host specificity in symbiotic interactions. At the USDA, I use bioinformatics to elucidate the ecology and evolution of plant diseases and their insect vectors.
