David Saltzberg, Ph.D. (b. 1967) is an astroparticle physicist and the science consultant for the CBS television situation-comedy, The Big Bang Theory, checking scripts and meeting with the producers, writers, actors, set decorators, prop masters, costume designers etc. to help ensure scientific accuracy. He also writes a blog, The Big Blog Theory, that explains the science behind each episode.
David Saltzberg is a Professor of Physics and Astronomy at the University of California, Los Angeles (UCLA). He received a bachelor's degree in Physics in 1989 from Princeton University where he worked in the Princeton Cyclotron. He received his Ph.D. in Physics from the University of Chicago in 1994, where he measured the mass of the W boson at the Fermilab Tevatron and CDF detector. In 1995-97, he performed post-graduate work at CERN on the CHORUS experiment looking for ν μ to ν τ oscillations with a 1-ton photographic emulsion target. Saltzberg returned to the U.S. and CDF as a faculty member at UCLA where he and his group helped build the CDF Run-II detector at the Fermilab Tevatron. His group looks for signs of supersymmetry and measures exotic properties of the top quark. Saltzberg's current interests are high energy particle physics and high-energy neutrino astronomy, using radio detection techniques. He is currently working on the ANITA project, which recently completed three successful scientific balloon flights in Antarctica, and also collaborating with the CMS experiment at the Large Hadron Collider at CERN.
