Gunnar Luderer is a senior researcher in Research Domain III - Sustainable Solutions.  He leads the Global Energy Systems Group within PIK's Research Domain III. He was a lead author of the 2013 UNEP Gap Report, and a contributing author to the Fifth Assessment Report and the Special Report on Renewable Energy Sources of the Intergovernmental Panel on Climate Change. He studied Physics, Economics and Atmospheric Sciences at the University of Heidelberg and Oregon State University. He performed his doctoral studies at the MPI for Chemistry in Mainz. Before joining PIK in October 2007, he worked in the Climate Policy Unit of the German Federal Environment Agency. Click here for a more detailed CV.
