I am an ecologist with broad interests in freshwater ecosystem structure and function with a focus on the role of consumers in biogeochemical cycling. Specifically, how losses of biodiversity and changes in community structure affect species interactions (food web interactions) and ecosystem function (nutrient cycling). I use ecological stoichiometry as a framework to examine how species traits, especially stoichiometric traits, influence ecosystem processes. I employ field, mesocosm, and laboratory studies to understand these interactions and process.

I received my B.S. in ecology and my M.S in Biology from Idaho State University in 2001 and 2006, respectively, and my PhD in Zoology from Southern Illinois University in 2013. Currently, I am a postdoctoral researcher at Arizona State University, working with Drs. James Elser and John Sabo on a project funded through a joint partnership with ASU SOLS and the Smithsonian Tropical Research Institute (STRI) working with Dr. Benjamin Turner. We are characterizing consumer-resource stoichiometry across environmental gradients and quantifying the mechanisms (e.g. body stoichiometry, trophic ecology, threshold elemental ratios, and growth efficiencies) behind these patterns and the interacting and independent influences of the abiotic environment.
