Biography
The lab's current research spans ecological scales, with spatially- and temporally-broad studies complemented by mechanistic ecophysiological investigations. Current interests include: global change ecology, especially manipulations of precipitation extremes (droughts and deluges), and large-scale comparisons of ecosystem sensitivity to climate, fire, grazing, and nutrients. Most of our research is conducted in grasslands, which are ecologically and economically important systems that respond rapidly to change and are amenable to field manipulations. Collaborative, interdisciplinary research is appealing and important to us because it provides scientists the opportunity to make key contributions within the specific framework of a single discipline (a traditional approach), as well as the tools to synthesize across disciplines and tackle issues that the single lab approach cannot. This synthetic approach to Ecology will become more important in the future, and it best describes our group's current and future research interests
