We are physiological ecologists interested in interactions between plants (principally trees) and their abiotic environment. Specifically, we focus on the impacts of climate change on terrestrial ecosystems, and feedbacks of vegetation to the climate system. We use a combination of field measurements, remote sensing, laboratory analyses, as well as modeling and statistical analysis of large data sets, in our research. We are interested in both above- and below-ground processes, at spatial scales and levels of integration from individual stomata to entire ecosystems, and from leaves and roots to the biosphere.
