Broadly our lab studies how changes in climate and land-use affect ecosystem processes that drive biogeochemical cycles of carbon and nitrogen. We are particularly interested in the question of how plant roots and soil microorganisms interact to affect soil carbon and nutrient dynamics. Within this framework we evaluate how elevated atmospheric CO2 concentrations, changes in temperature and precipitation, and land-use change for cellulosic biofuel production affect the quantity and quality of root and litter derived soil carbon input, and we determine implications for soil carbon sequestration.
Empirical methods for remote sensing of nitrogen in drylands may lead to unreliable interpretation of ecosystem function.
