Dr. Stephen M. Ogle is the coordinator for the ALU software project.  He is a Research Scientist and Associate Professor at Colorado State University, and an expert on application of greenhouse gas inventory methods.  He serves as lead compiler for the US national inventory for soil C and nitrous oxide emissions from agricultural lands, in addition to the US national representation of land. These inventory products are used for reporting by the US government to the United Nations Framework Convention on Climate Change (UNFCCC). He has been a lead author on syntheses and reports prepared by the Intergovernmental Panel on Climate Change (2006 National Greenhouse Gas Inventory Guidelines and Fourth Assessment Report on Climate Change), and a past member of the scientific steering group for the North American Carbon Program. He also conducts research collaboratively with economists and sociologists to better understand the drivers of land use and management decisions, and predict the likelihood of greenhouse gas mitigation in the future through adoption of conservation practices and bioenergy production in agricultural lands. Dr. Ogle has participated in international capacity-building projects to improve greenhouse gas inventory compilation in Central America, South Asia, Southeast Asia, and Eastern and Southern African Countries, providing training and tools on greenhouse gas inventory methods for the Agriculture and Land Use, Land Use Change and Forestry sectors.
