Postdoctoral Experience:

Research Interests:

Evolutionary Ecology; Population & Evolutionary Genetics; Coevolution; Plant-Herbivore-Enemy Interactions

Research Program:

I am interested in ecological interactions among plants and their herbivores and pathogens, and in the adaptive significance of genetic variation in natural populations of insects. Since 1984, I have studied populations of the leaf beetle Chrysomela aeneicollis in the Sierra Nevada mountains of California, focusing first on effects of insect predators on host plant suitability, and then on population and genetic responses to thermal variation in montane populations. I have also collaborated with researchers in Europe on plant-herbivore interactions in related insects. Finally, I am interested in effects of invasive species on native ecological communities. Ongoing work in this area focuses on the invasive pathogen Phytophthera ramorum, which has spread through Sonoma County woodlands since 2000.
