Our Research: We use a systems modeling approach to understand, quantify, and predict ecosystem processes and patterns in response to climate change, land use, land management, and atmospheric composition at multiple scales from watershed, landscape to regional, national, and global.  Our work involves mathematical modeling, large-scale data development, data-model integration, geospatial and statistical analysis. Overall, it can serve as a powerful tool for assessing the provision of ecosystem goods and service, and identifying better management practices and mitigation options for a sustainable earth
