Ben Poulter is an ecosystem ecologist. He studies how ecosystems respond to climate change, rising atmospheric CO2 concentrations, disturbance, and land management. To carry out this work, he integrates ecological theory, field observations, and remote sensing data, within land-surface models. The land-surface models can then be used to test hypotheses on why ecosystems are changing and how they will continue to change in the future. Ben Poulter has contributed to the Intergovernmental Panel on Climate Change Assessment Reports (5th and 6th), and currently serves as Co-Chair for the Integrated Land Ecosystem Atmospheres Study (iLEAPS), a Global Research Project of Future Earth, and on the science leadership group for the US Carbon Cycle Science Program North American Carbon Program (NACP). He is Co-Lead for Research and Applications for the NASA Surface Biology and Geology Designated Observable, an imaging spectroscopy and thermal emissivity mission.
