William J. Weber

Governor’s Chair Professor


Dr. William J. Weber earned his B.S. Cum Laude in Physics from the University of Wisconsin, Oshkosh in 1971, and his M.S. and Ph.D. in Nuclear Engineering from the University of Wisconsin, Madison in 1972 and 1977, respectively. His dissertation research included transmission electron microscopy analysis of the temperature dependence of void and dislocation loop formation in ion-irradiated vanadium. From 1977 to 2010, Dr Weber was on the staff of the Pacific Northwest National Laboratory (PNNL) where he conducted research on radiation effects in ceramics and glasses, the long-term behavior of nuclear waste forms, electronic and ionic transport in ceramics, solid oxide fuel cells, high-temperature superconductors, and physics of radiation detectors. He was appointed Laboratory Fellow at PNNL in 1997 and served as Chair of the PNNL Council of Fellows from 2005 to 2009. In 1983, he was a visiting scientist at the Institute for Transuranium Elements in Germany, where he studied radiation effects in actinide compounds, nuclear waste glasses, and nuclear fuel materials. From 1989 to 1993, he was on a special assignment to the Office of Basic Energy Sciences, US Department of Energy, where he provided technical assistance in the review and evaluation of materials sciences programs. Dr. Weber joined the faculty at the University of Tennessee in 2010 as the UT-ORNL Governor’s Chair for Radiation Effects on Materials.

Dr. Weber’s research group focuses on the fundamental and applied aspects of radiation effects in materials, interaction of radiation and charged-particles with solids, ion-beam and electron-beam modification of materials, defect-property relationships in ceramics, long-term performance of materials under extreme environments, phase transformations, interface phenomena, and nanostructures in materials. Their research includes using energetic ion and electron beams to study radiation effects in materials, to structurally modified materials for advanced technologies, and to perform accelerated testing of materials for extreme radiation environments, as well as using advanced computational methods to investigate defect properties, phase transformations and radiation effects. Dr. Weber is a Fellow of the American Ceramic Society, Materials Research Society, and American Association for the Advancement of Science. He has received an Outstanding Young Alumni Award (1983) and Distinguished Alumni Award (2009) from the University of Wisconsin-Oshkosh; the PNNL Laboratory Director’s Award for Individual Lifetime Achievement in Science & Technology (2009); and the PNNL Chester L. Cooper Mentor of the Year Award (2005). He has published more than 500 technical papers that have been cited more than 7700 times. He has chaired numerous international conferences, society symposia, topical workshops.
