Naoki Kishimoto, born in Osaka, Japan in 1949, received Doctor of Science at University of Tokyo, March 1977, majoring metal-nonmetal transition of amorphous Si-Au System. Since 1978, he worked for National Research Institute for Metals, mainly on radiation damage study of metal and semiconductors. Since 2001, the institute was reorganized as National Institute for Materials Science (NIMS) combining metal and ceramics institutes. He has been engaged in a program of nanodevice development using ion implantation. He is now Director of Nanofunction Group in Nanomaterials Laboratory, NIMS, and is co-assigned as Professor of University of Tsukuba and Director of Integrated Strategy Office, NIMS. His main research interest is development of nonlinear optical materials of metal/semiconductor nanoparticles using ion and laser beams.
