Deborah K. Letourneau's Bachelor's, Master's and doctoral degrees are from the University of Michigan and University of California at Berkeley. As Professor of Environmental Studies at the University of California, Santa Cruz her research concerns plant-insect interactions, biodiversity, and environmental risk in the context of decision-making that sustains both livelihoods and the environment.

Anurag A. Agrawal studies the evolutionary ecology of plants and insects as a professor at Cornell University's Department of Ecology and Evolutionary Biology and Department of Entomology. His work spans community ecology, invasive species, coevolution, and ecological genetics. Please visit his lab website www.herbivory.com for current projects and research.
