I am a Research Professor of Earth System Science in the Institute for the Study of Earth, Oceans, and Space, jointly appointed in the Dept. of Earth Sciences, and Faculty Chair of the interdisciplinary Natural Resources and Earth System Science PhD Program. I earned a B.S./M.S. in Physics from UNH, a Ph.D. in Earth Sciences/Biogeochemistry from UNH, and was a post-doc in NOAA’s Program in Climate and Global Change. My research focus is on the interaction between natural and/or managed terrestrial ecosystems and the climate system, in the context of climate and global change. I have active research in several areas within the broader field of Earth System Science: (1) peatland carbon balance and long-term carbon accumulation, including consequences of land use and permafrost thaw; (2) water resources and sustainability in the 21st century; (3) global land use, including carbon and nitrogen cycling in agroecosystems at regional to global scales; and (4) remote sensing analyses of global urban change. Research tools include ecosystem and hydrological modeling, remote sensing, and data analysis, and generally involve interdisciplinary collaborations.
