Ian Kraucunas is Deputy Director of the Atmospheric Sciences and Global Change Division, which includes over 80 scientists and engineers from a wide range of disciplines. He also leads the Earth System Modeling and Analysis group, which focuses on improving and applying climate models and related tools to better understand and project Earth system changes and impacts. Previously, he led PNNL's Platform for Regional Integrated Modeling and Analysis (PRIMA) initiative, a laboratory-wide activity to bring together modeling capabilities spanning the climate-energy-water-land nexus.

Prior to joining PNNL, Ian was a Senior Program Officer with the Board of Atmospheric Sciences and Climate at the National Research Council (NRC), the operating arm of the National Academy of Sciences, where he played leadership roles in a number of climate-related reports and activities. He received his Ph.D. in Atmospheric Sciences from the University of Washington, where his graduate research focused on developing and applying idealized numerical models of the large-scale circulation of the tropical atmosphere.
