Water cycles and biogeochemical cycles are connected at multiple temporal and spatial scales, and are connected from both economic and scientific point of view. Anthropogenic activities constantly create or interrupt connectivity between water cycles and biogeochemical cycles and raise the needs to better understand such connectivity. My general research interests are studying spatial and temporal patterns of water and nitrogen availability, how vegetation adapts to and affects such patterns, and how future climate/land use changes affect vegetation-resources interactions. I use a variety of research tools, including analyses based on stable isotopes, manipulative experiments, field observations, geostatistical methods, greenhouse experiments and process-based modeling to tackle these questions.
