Belowground Carbon Dioxide Cycling in a Desert Ecosystem
An understanding of the mechanistic links between biological, chemical, and physical processes is critical to address the environmental problems facing society today. The fields of ecosystem ecology and environmental science are focused on how organisms in their natural habitats are affected by biotic and abiotic factors, and how these organisms in turn modify their environment.
My primary research interests are in ecosystem ecology, particularly the biogeochemical cycling of carbon and water within terrestrial ecosystems. Work in my lab focuses on examining carbon and water relations of plants and soils at the ecosystem scale, with the principal goals of understanding 1) ecosystem physiological processes, 2) factors influencing the carbon and hydrological cycles within ecosystems, 3) biosphere-atmosphere fluxes of carbon dioxide, water vapor, and their isotopes, and 4) ecosystem water balance, particularly in ecosystems of the western United States. This work is interdisciplinary in nature, requiring collaboration with colleagues from a variety of scientific disciplines, including plant physiology, soil science, hydrology, micrometeorology, and geochemistry.
