Dr. Ralph Cicerone was elected the President of the National Academy of Sciences on February 7, 2005. Among his many achievements in shaping policy on climate change, global warming and pollution was the landmark study Climate Change Science: An Analysis of Some Key Questions, which was conducted by the National Academies at the request of the White House. Dr. Cicerone's work as an atmospheric chemist includes research on the plasma physics of Earth's ionosphere, the chemistry of the ozone layer and radiative forcing of climate change. He was elected to the NAS in 1990 and has been an active member of its Council since 1996. His work has been honored by the American Geophysical Union with its James B. Macelwane and Roger Revelle medals, and the Franklin Institute gave him the Bower Award and Prize for Achievement in Science. His research has received worldwide recognition from the World Cultural Council and the United Nations. Prior to becoming the president of the NAS, Dr. Cicerone was the chancellor at the University of California's Irvine campus, where he was one of the few heads of a major research university to maintain his own laboratory. Dr. Cicerone's distinguished career as a research scientist, a university professor and administrator began at the Massachusetts Institute of Technology, where he studied electrical engineering and was a varsity baseball player. After graduating from MIT, Dr. Cicerone received his masters and doctoral degrees in electrical engineering from the University of Illinois, Urbana-Champaign.
