Short Biographical Sketch:
Professor Williams joined the faculty at Washington and Lee in 1974, and retired from full-time teaching in the summer of 2011. He attended the University of Virginia, receiving a B. S. in Physics in 1963 and a Ph.D. in Physics (under the direction of M. E. Rose) in 1967.
Upon completion of the Ph.D. he was awarded a National Research Council / National Science Foundation Postdoctoral Research Fellowship which funded two years of theoretical research (with M. Danos) at the National Bureau of Standards, in Washington, DC. He then spend three semesters as Gastdozent at the Universitaet Erlangen-Nuernberg in Germany, followed by a one term teaching appointment at the Virginia Military Institute in Lexington, Virginia.
From the fall of 1971 through the end of 1973, he served as a staff scientist at Kaman Sciences, Colorado Springs, Colorado, studying electromagnetic shielding, field propagation, transmission and reception.
In January 1974, Dr. Williams was appointed Assistant Professor of Physics at Washington and Lee. He was promoted to Associate Professor in 1979, and to Professor in 1984. For the three academic years spanning 1986-89 he served as Associate Dean of the College of Arts and Sciences, and served as Head of Physics and Engineering from 1989 until June, 2000. During the academic year 2002-03, he served as Acting Dean of the College. From 2003-07 he was University Provost. In the fall of 2007 he returned to the Department of Physics and Engineering and served as Department Head in 2010 and 2011.
Professor Williams has provided consulting services to the National Bureau of Standards and the Los Alamos National Laboratory. He has received research support from the National Bureau of Standards, Los Alamos National Laboratory, the Research Corporation and the National Science Foundation.
Professor Williams continues to pursue research areas in the areas of quantum information theory and non-equilibrium statistical mechanics involving both analytical approaches and computer simulations to address one-dimensional systems.
