With a focus on how biophysical factors regulate carbon and water dynamics in terrestrial ecosystems. Specifically, studying soil-plant-atmosphere interactions to understand the response of terrestrial ecosystems to management, extreme events, and global change. I am interested in studying above- and below-ground processes at multiple spatio-temporal scales and vegetation types.
