Areas of Interest
Plant & Soil Ecology; Global Change Ecology; Biogeochemistry
My research primarily involves the integration of observational and experimental approaches in field-settings to understand global change impacts on terrestrial ecosystems. Much of this work involves the application of stable carbon and nitrogen isotope, tracer techniques and, where necessary, the use of controlled-laboratory manipulations to tease apart competing mechanistic hypotheses.
