am interested in the ways in which trophic interactions and resource
productivity influence community composition. My approach to
understanding communities lies at the interface between quantitative
theory and real systems. In my current work, I am developing
community theory that extends existing
trophic cascade theory to allow within-trophic level compensation and
account for whole-community stoichiometric constraints. This
spring, I will begin to test this theory with broad-scale experiments
in West Coast grasslands,
focusing on the community-level (primarily plant and insect) effects of
altered nitrogen deposition and exotic plant invasions. I am also
collaborating with several researchers on a project to examine the
long-term implications of an aphid-vectored disease, Barley Yellow
Dwarf Virus, on West Coast grassland community composition.
My recent projects include synthesizing the divergent theoretical literature on intraguild predation and testing this theory with empirical data to examine the role of intraguild predation in structuring communities. My other work includes examining where and why trophic cascades occur, mechanisms of coexistence in biological control, and top-down and bottom-up effects in food webs.
