"Predicting Soil Organic Carbon and Greenhouse Gas Dynamics using State-of-art Biogeochemical and Machine Learning Models"
The fate of land-atmosphere exchange of CO2, CH4, and N2O remains uncertain under current and future climate, partly due to our limited understanding of belowground processes. I address these critical knowledge gaps by coupling subsurface soil process measurements with surface chamber fluxes and landscape-scale fluxes to allow the scaling-up of process-based (and data-driven) models and soil-flux measurements to the ecosystem scale. In this talk, I will explore existing theories of biology, physics, chemistry, and mathematics to advance understanding and prediction of biogeochemical feedbacks in terrestrial systems using case studies ranging from the tropics to sub-boreal ecosystems, and soils from forests, wetlands, grasslands, and agricultural landscapes.
