I received my BSc in Engineering Physics at Colorado School of Mines in Golden (1975), then continued my graduate work at SUNY-Stony Brook, where I received a Ph.D. in physics in 1980. I did post-doctoral research at Princeton University (1980-83), NORDITA in Copenhagen and Helsinki University of Technology (1983-84), then joined the Princeton physics faculty (1983-1987). Since 1987 I have been a professor of Physics at Northwestern University in Evanston, Illinois. Theoretical condensed matter research involves the discovery of new concepts related to the collective behavior of enormous numbers of atomic constituents, combined with the application of statistical mechanics and quantum theory to describe the behavior of macroscopic matter. This behavior is clearly revealed at low temperatures, or in the presence of strong electromagnetic or acoustic radiation fields where quantum effects are important. Matter under such conditions is described by quantum field theory. I conduct theoretical studies of matter in which quantum effects are manifest in the observable properties of matter.
