Research Interests
I am broadly interested in the ways that the traits or behavior of individuals can scale up to influence the structure and dynamics of ecological communities.  Using laboratory and field experiments, my research examines how biotic and abiotic stress influence the behavior, fitness, and physiology of consumers and the indirect effects of these stressors on community structure and ecosystem function.
