Principal Investigator
I am a community ecologist who wants to understand how food webs ‘work.’ I am interested in interspecific interactions and how these interactions affect community structure. I seek to design and conduct field experiments testing both basic and applied ecological questions, in collaboration with researchers from a range of fields. I use large-scale geographic surveys in combination with manipulative experiments to document general patterns of plant-animal interactions and answer questions generated by these patterns. My current research projects include several different projects related to the hemlock woolly adelgid (interactions between it and other hemlock herbivores, the development of adelgid-resistant eastern hemlocks), a series of collaborations that examine predator-prey interactions (effects of prey behavior on predator survival and reproduction, comparisons of plant-herbivore and predator-prey interactions), and an international collaboration with Chinese researchers into the community ecology of the sweetpotato whitefly…Learn more
