Professor Emeritus


In the past Professor Gerjuoy published predominantly, though not entirely, in atomic physics collision theory. More recently, however, he has been devoting his research time solely to various theoretical problems related to quantum computing. During much of his career as a physicist he has worked on various American Physical Society (APS) and other professional society committees. In particular, he has been a member (and in some years Chair) of the following APS Committees: Panel on Public Affairs (1976-79, 1981 and 1994-96); Audit Committee (2002-4); Constitution and Bylaws Committee (1999-2002). In addition he has been a member (2000-03) of the APS Council, the APS governing body, as well as an officer (including Chair) of the APS Forum on Physics and Society (1994-7); membership (2005-07) on the APS Sakharov Prize Committee was his most recent APS committee service. In past years he also has been a member of: the Oak Ridge National Laboratory Health Physics Division Advisory Committee (1967-70, Chair 1971-74); the National Conference of Lawyers and Scientists, a joint Committee of the American Association for the Advancement of Science and the American Bar Association (1986-92); and the Pennsylvania Environmental Hearing Board (1981-86). These last two appointments reflect the fact that Professor Gerjuoy earned a law degree in 1977; indeed he has published numerous papers on issues arising at the interface of law and science.
