Professor of astronomy and astrophysics, elected to the American Philosophical Society on April 29. Ph.D. in astronomy from Harvard University. She joined the faculty of UCSC and the UC Observatories/Lick Observatory in 1972. Faber is renowned for her research on the formation and evolution of galaxies and the evolution of structure in the universe. She has made significant scientific contributions in the areas of structure and formation of elliptical galaxies; the nature, compositions, and motions of stars within a galaxy as related to their ages; and the streaming motions of large numbers of galaxies. Important concepts such as "cold dark matter" and the "Great Attractor" are direct results of work by Faber and her colleagues. Faber's many honors include election to both the National Academy of Sciences and the American Academy of Arts and Sciences.
