Dr. Ogle gained an appreciation for research as an undergraduate studying in the laboratory of Dr. Don Shure at Emory University, and did his formal training as a graduate student with his mentor, Dr. Bill Reiners at the University of Wyoming. Dr. Ogle accepted a post-doctoral position with Dr. Keith Paustian at Colorado State University in 2000. His research focused on research dealing with biogeochemical processes related to greenhouse gas emissions from Agriculture, Forestry and Other Land Uses (AFOLU), and developing a greenhouse gas inventory in compliance with IPCC guidelines. He has become an expert on research and application of greenhouse gas inventory methods. Since 2003, he has served as the lead technical compiler for the US national inventory for soil carbon and nitrous oxide emissions from agricultural lands, in addition to the US national representation of land. He also leads compilation of inventories for rice methane, grassland and agricultural residue burning emissions, and liming carbon dioxide emissions. He has been a lead author on syntheses and reports prepared by the Intergovernmental Panel on Climate Change (2006 National Greenhouse Gas Inventory Guidelines, Fourth Assessment Report on Climate Change, 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories), and is member of the scientific steering group for the International Soil Carbon Network.
