Carbon Cycle And Ecosystems

Employed By



"My research interests are centered around improving our mechanistic understanding of the terrestrial carbon cycle. I approach this problem using large observational datasets, in particular, much of my research has employed chemical transport models and data assimilation methods to infer net biosphere-atmosphere carbon fluxes from measurements of atmospheric CO2. I use these constraints, in combination with complementary datasets of vegetation function (e.g., solar induced fluorescence) and environmental variables (e.g., temperature and moisture reanalysis) to investigate the relationship between climate (and climate variability) and the carbon cycle of terrestrial ecosystems."
