Professor Elbaum received the Master's and Ph.D. degrees from the University of Toronto. He was a Research Fellow at the University of Toronto and at Harvard University before joining the faculty at Brown University in 1959 and has since then also carried on research at the University of Paris. Professor Elbaum has been a frequent advisor to government and industrial research laboratories. He is a Fellow of the American Physical Society. Professor Elbaum served as Chairperson of the Physics Department from 1980 to 1986. In 1991 he was appointed the Hazard Professor of Physics.
