My laboratory’s research program focuses on interactions among three important drivers of ecosystem function and community structure: energy input, nutrient availability, and temperature. While our research leverages the unique characteristics of streams and their suitability for ecosystem-level research, we concentrate on broad questions that are also relevant to other ecosystem types. A major goal for our research program is to integrate the metabolic theory of ecology, with its emphasis on temperature and body size, with the explicit multiple-element approach to resource limitation that is central to ecological stoichiometry theory. Although guided by theory, our research has a strong empirical focus, spans scales from the individual to the ecosystem, and often exploits both natural landscape gradients and experimental manipulations at the ecosystem level.
