Research Interests

I use general ecological theory spanning the hierarchy levels of ecology to address contemporary issues in aquatic ecology and biodiversity conservation. For example, in my research I use organismal-level theory (e.g., metabolic theory, natural selection, etc), population-level theory (dynamic modeling, etc.), community-level theory (e.g., food web modeling, etc.), and ecosystem-level theory (e.g., ecological stoichiometry) to understand the link between organism distribution/abundance to abiotic and biotic context of aquatic ecosystems. My goal is to help generate general models that may be used to predict how ecosystem change (anthropogenic or natural) may affect aquatic biodiversity and ecosystem processes at local and regional scales. I have used this approach to contribute to general theoretical issues in ecology as well as tackle specific applied conservation issues for endangered species managers.
