Ben Kravitz is an expert in climate modeling studies of solar geoengineering. He is the co-founder and coordinator of the Geoengineering Model Intercomparison Project (GeoMIP), a collaboration between climate modeling centers throughout the world to better understand the expected climate effects of various geoengineering scenarios. Results from GeoMIP are featured in the Fifth and Sixth IPCC assessment reports, for which Ben serves as a contributing author, the 2015 National Research Council reports on climate intervention, and recent testimony to Congress. Ben is an assistant professor at Indiana University in the Department of Earth and Atmospheric Sciences, and he maintains a joint appointment in the Atmospheric Sciences and Global Change Division at Pacific Northwest National Laboratory. In addition to coordinating and participating in GeoMIP, his current activities include using engineering and mathematical techniques in climate models to better understand climate feedbacks, studying teleconnections in high latitude climate, and developing climate model emulators for use in Integrated Assessment Models.
