Oskar Franklin joined IIASA’s Forestry Program, now Ecosystems Services and Management (ESM) Program in June 2004, where he developed forest models for the prediction of forest greenhouse gas fluxes in response to management options. Recently, he worked on ecosystem theory and models of boreal forests under global change and the role of mycorrhizal symbiosis for carbon and nutrient cycling. He also led a Greenhouse Gas Initiative (GGI) project that initiated the development of a new generation forest and vegetation model that takes advantage of ecological and evolutionary principles to better constrain predicted consequences of climate change.
Dr. Franklin received his PhD in systems ecology at the Swedish University of Agricultural Sciences in Uppsala in 2003. His work involved optimal plant theory and forest growth responses to nitrogen and carbon dioxide. Prior to becoming involved in ecology, he earned an MSc degree in physics engineering at Uppsala University, and worked at the Swedish Radiation Protection Institute with nuclear power emissions and environmental effects.
