Interests and Expertise

I’m an ecosystem ecologist working to discover how plants, animals, and microbes interact within rivers and how the results of those processes influence how people and society interact with rivers. In collaboration with my colleagues, I make biogeochemical measurements, perform experiments, and interpret results using statistical models and analysis. I’m particularly interested in developing new measurement technologies for aquatic environments, exploring how sea level rise affects rivers, and implementing conservation techniques that improve both ecological conditions and the utility people derive from freshwater ecosystems.
