Susan Solomon is a recognized world expert in atmospheric science. Since receiving her Ph.D. in chemistry from the University of California at Berkeley in 1981, she has been employed by the National Oceanic and Atmospheric Administration as a research scientist. Her research has provided key measurements and critical theoretical understanding of stratospheric ozone destruction. In 1986 and 1987, she served as the Head Project Scientist of the National Ozone Expedition at McMurdo Station, Antarctica, and made some of the first measurements that pointed toward chlorofluorocarbons as the cause of the ozone hole. In 1994, an Antarctic glacier was named in recognition of her contributions to polar science.
