Dr. Kraucunas is the director of the Atmospheric Sciences and Global Change Division at Pacific Northwest National Laboratory. The division has over 140 staff with expertise ranging from fundamental atmospheric physics to regional and global climate modeling to integrated assessment and climate impact analysis. He also serves as principal investigator for the "Integrated Multi-sector, Multi-scale Modeling (IM3)" scientific focus area, a multi-institution Department of Energy project focused on developing and applying integrated modeling platforms that can simulate the complex interactions among climate, energy, water, land, and other human and natural systems. Prior to joining PNNL, Dr. Kraucunas was a senior program officer with the Board on Atmospheric Sciences and Climate at the National Research Council of the National Academy of Sciences, where he led a number of projects and repots related to climate and global change research. Dr. Kraucunas received a Ph.D. and M.S. in Atmospheric Sciences from the University of Washington, Seattle, and a B.A. in Physics and Environmental Science from the University of Virginia.
