John Schroeder

Prior to joining the faculty of Rensselaer in January, 1982, he was a commissioned officer in the U.S. Navy from June, 1962, to January, 1970. From 1975 to 1978 Professor Schroeder was a Post-Doctoral Associate in the School of Chemical Sciences and a Senior staff member of the Materials Research Laboratory at the University of Illinois in Champaign/Urbana. In l978, he joined the General Electric Corporate Research and Development Center in Schenectady, NY. He did basic glass and ceramic material research and examined material behavior at ultra high pressure (diamonds). At Rensselaer he studied the optical and magnetic properties of glasses using Rayleigh, Brillouin and Raman spectroscopic techniques at extremes of pressure and temperatures. Recently Schroeder has worked on confirming the existence of intermediate range order in glasses leading to an explanation of the existence of non-exponential structural relaxation in glasses. He also leads a program of optical characterization of nanocrystalline (II-VI and IV) semiconductors with high pressure being a most important parameter. Now, he also works on the problem of cataract formation in the human lens employing photoluminescence spectroscopy and perturbative colorimetry techniques. Schroeder is the author or coauthor of over 110 published technical articles in refereed journals and proceedings. Under Schroeder’s guidance ten Ph.D. thesis students and eight M.S. students have completed their degrees. He has also supervised undergraduate research participants for over twenty students.
