Takeshi Egami

UT-ORNL Distinguished Scientist/Professor Director, Joint-Institute for Neutron Sciences


Dr. Egami received his Bachelor’s degree in Applied Physics from the University of Tokyo in 1968, and his Ph.D. in Materials Science from the University of Pennsylvania in 1971.  After the postdoctoral research at the University of Sussex, U.K. and Max-Planck-Institute in Stuttgart, Germany, he returned to the University of Pennsylvania in 1973 as Assistant Professor. He was promoted to Associate Professor in 1976, to Professor in 1980, and was the Chair of the Department of Materials Science and Engineering from 1997 to 2002. He moved to the current position in 2003. He had guest appointments at Los Alamos National Laboratory (2002), KEK (High Energy Accelerator Research Organization), Tsukuba, Japan (1998), Inst. for Materials Research, Tohoku University, Sendai, Japan (1993), IBM Almaden Research Lab, San Jose (1988), Department of Physics, University of Tokyo, Tokyo, Japan (1987), and Max-Planck-Institut fur Metallforschung, Institut fur Physik, Stuttgart, Germany (1979-80). Dr. Egami has authored or co-authored 1 book, about 20 full reviews and over 360 technical papers. He gave over 200 invited technical presentations at national and international conferences.
