Statement
The overall goal of my research is improve our understanding of the mechanisms by which natural and human-modified ecosystems both respond to and feedback on global environmental change. Current work in my lab is focused on understanding how changes in vegetation structure affect climate processes and the cycling of carbon and water at regional scales. To do this, we study the ecological and physical processes that control fluxes of carbon, water, and energy between the biosphere and the atmosphere. We use a wide array of methods including ecophysiological measurements, micrometeorological techniques, numerical modeling, and remote sensing. An important focus of our work is to use these tools in combination to bridge the gap in scales between ecosystem and global studies. Our approach is interdisciplinary, borrowing concepts and tools from atmospheric science, biogeochemistry, environmental physics, hydrology, and plant physiology to address large-scale ecological questions. The current projects in my lab provide opportunities for students with interests in a wide array of questions related to global change and terrestrial ecosystems.
