Alexandra Navrotsky is a physical chemist in the field of nanogeoscience. She is an elected member of the United States National Academy of Sciences (NAS). She was a board member of the Earth Sciences and Resources division of the NAS from 1995 until 2000. In 2005, she was awarded the Urey Medal, by the European Association of Geochemistry. In 2006, she was awarded the Harry H. Hess Medal, by the American Geophysical Union. She is currently the director of NEAT ORU (Nanomaterials in Environment, Agriculture, and Technology Organized Research Unit), a primary program in nanogeoscience. She is Distinguished Professor at University of California, Davis.
She graduated from Bronx High School of Science in New York. She received B.S. (1963), M.S. (1964), and Ph.D. (1967) in physical chemistry from University of Chicago, where she studied with Professor Ole J. Kleppa. In 1967, she went to Germany for postdoctoral work. She came back to the U.S. in 1968 and continued her postdoctoral work at Pennsylvania State University. Then she joined the Chemistry faculty at Arizona State University, for approximately five consecutive years. Later on, she moved to the Department of Geological and Geophysical Sciences at Princeton University in 1985. She became the chair of that department from 1988 to 1991. In 1997, she moved to University of California at Davis and became an Interdisciplinary Professor of Ceramic, Earth, and Environmental Materials Chemistry. In 2001, she was chosen as the Edward Roessler Chair in Mathematical and Physical Sciences. As of 2013, she was appointed interim dean of Mathematical and Physical Sciences in the College of Letters and Sciences, at University of California at Davis. Her specializations include: Solid-state chemistry, Ceramics, Physics and Chemistry of Minerals, Geochemistry.
