My research focuses on the role of hydrological processes in the functioning of terrestrial ecosystems. Through the analysis of the soil water balance I have highlighted important nonlinearities in the coupling between soil moisture dynamics and plant water stress, biogeochemical cycling, land-atmosphere interactions, plant community composition, and soil susceptibility to wind erosion. Using field observations and process-based models, I am investigating new mechanisms of desertification and factors contributing to the resilience of the desert margins. Our group's work has highlighted the role played by positive feedbacks with the physical environment on the resilience of savannas, dry tropical forests, desert shurblands, freshwater wetlands, mangrove swamps, and seagrass meadows. Our work has also shown how environmental noise may increase the complexity of ecosystem dynamics by inducing new states, bifurcations, or pattern formation. I am currently investigating the globalization of water through virtual water trade and international land investments, and its impact on water equity, societal resilience, environmental stewardship, and food security.
