I am a scientist with the U.S. Geological Survey and a member of the Southwest Biological Science Center. My research interests are centered within the fields of biogeochemistry and ecosystem ecology. Currently, I study terrestrial ecosystems in Utah, Arizona, New Mexico, California, Colorado, Hawai’i, Puerto Rico, Bolivia, Perú, and Costa Rica. While my study sites and the methods I use are diverse, with each of my projects I strive to determine the dynamic controls over fundamental ecosystem processes with the ultimate goal of providing information to help maintain the desirable features of Earth’s ecosystems in a world that is rapidly changing.
