Robert Socolow is professor emeritus and a full-time member of the senior research staff in the Department of Mechanical and Aerospace Engineering at Princeton University. In his research he seeks new conceptual decade-scale frameworks that are useful forclimate change policy. With colleagues heintroduced “stabilization wedges,” “one billion high emitters,” “committed emissions,” and “destinystudies.” He is engaged with multi-disciplinary efforts to anticipate key issues associated low-carbonfutures,including analyses of energy efficiency in buildings, wind and solar power, nuclear fission andfusion power, CO2 capture and storage from fossil fuels and the air, impacts on the land whenbiocarbon is priced, and technological “leapfrogging” by developing countries. He is a member of theAmerican Academy of Arts and Sciences, an associate of the National Research Council of the NationalAcademies, a fellow of the American Physical Society, a fellow of the American Association for theAdvancement of Science, and the recipient of the Leo Szilard Lectureship Award by the AmericanPhysical Society. He earned his Ph.D. from Harvard University in theoretical high energy physics in 1964and joined the Princeton University faculty in 1971.
