Marc Davis is a Professor of Astronomy and Physics at the University of California, Berkeley. Davis received his bachelor's degree from the Massachusetts Institute of Technology in 1969, his Ph.D from Princeton University in 1973 and has been elected to both the National Academy of Sciences and the American Academy of Arts and Sciences. Davis taught for a year at Princeton, 1973â€“74, then served on the Astronomy faculty at Harvard from 1975 to 1981. Since 1981 he has been on the faculty of the Department of Astronomy and Physics at the University of California at Berkeley.
Davis' work has been in physical cosmology and he has done a number of significant projects. While at Harvard, Davis led the CfA galaxy survey, the first redshift survey of galaxies, which motivated his interest in nbody simulations of the Universe. In the 1980s, Davis, now at Berkeley, was part of a collaborationâ€”with George Efstathiou, Carlos Frenk, and Simon Whiteâ€”that established the validity of the "cold dark matter" theory for the formation of galaxies and other cosmic structures, now the accepted interpretation in cosmology. In a classic series of papers, that collaborationâ€”often called DEFW by their peersâ€”used computer code to simulate the growth of the universe and resolve disputes among theoretical models.
