Cycles

Understanding global biogeochemical cycling requires upscaling of point measurements, modeling of process rates, and development of theory regarding how ecosystems function. We use a combination of observations, isotopic techniques, computational modeling, and theoretical research in order to contribute to an understanding of biogeochemical cycling at the global scale. This work includes using isotopes to understand denitrification losses, developing a framework for nitrogen fixation in soils, and contributing to science on undetected sources of nitrogen to terrestrial ecosystems.
