Biographical Information

My lab studies the ecology of food webs, ecosystems, and watersheds, and most of our research occurs in freshwaters. Current research areas include:

• Animal-mediated nutrient cycling, including understanding variation among individuals using principles of ecological stoichiometry and metabolic ecology, and the importance of animals at the ecosystem scale
• Long-term response of a lake (reservoir) ecosystem to changes in agricultural practices, and how internal processes such as animal-mediated nutrient cycling provide resilience in terms of the lake response
• How nutrients, light, and other factors mediate energy and nutrient flow through food chains

My lab takes a diverse approach to research, including whole-ecosystem studies, field and lab experiments, meta-analyses/syntheses, and modeling. In my lab, research is a collaboration among undergraduates, graduate students, postdocs and research associates.
