研究领域

I seek to understand the structure, composition, and functioning of terrestrial ecosystems. My specific interests are linked together by the idea of “scaling”, or the discovery of relationships between small-scale spatiotemporal ecosystem variability and large-scale ecosystem properties. The context of my research is that of environmental change: how do changes in climate or other exogenous forcings affect terrestrial ecosystems? My approach is to develop state-of-the-science numerical models that are capable of predicting ecosystem responses to environmental change
