As an aquatic biogeochemist, my research interests are widespread. The theme of my research is to understand the interaction between ecosystem structure and function. More specifically, I explore feedback loops between the physical habitat or vegetation present in an ecosystem (e.g, riffle-pool sequences in a stream and invasive vs. native species in wetlands) and the services provided by that ecosystem (e.g., nutrient removal and carbon sequestration). Because I specialize in streams and wetlands located in agricultural or urban watersheds, the projects that are most intriguing to me focus on nutrient and carbon dynamics.

Here at the University of Nebraska I am working on a project with John Lenters, Erkan Istanbulluoglu, Durelle Scott, and Xiaomao Lin examining the impact of invasive species removal on water quantity and water quality in the riparian corridor of the Republican River in south-central Nebraska. The three main components on this project are to measure evapotranspiration rates through Large Aperture Scintillometry (LAS) techniques, estimate regional water savings with the model Agro-IBIS, and measure changes in water quality and biogeochemical cycling. Stay tuned to this website for descriptions, photos, and real-time data from the riparian wetland we are studying in the Republican River Basin.
