Vegetation Ecology, Ecosystem Ecology, Biogeochemistry, Ecological Consequences of Global Change, Wyoming in the Earth System
I conduct research on carbon and water fluxes between terrestrial ecosystems and the atmosphere, and on the effects of global changes such as increasing carbon dioxide concentrations and land-use change on these fluxes. An important component of my work involves the use of stableisotopes as tracers to better quantify small changes in these fluxes that might not otherwise be detected. Much of my research focuses on belowground carbon pools and processes to better characterize their role in ecosystem responses to global change.
