Yasuhiko Hayashi received the B.E., M.E. and D.E., degrees in electrical and computer engineering from the Nagoya Institute of Technology, Nagoya, Japan, in 1990, 1992, and 1999, respectively. From 1992 to 1996, he was engaged in research on semiconductor device modeling in Motorola Japan Ltd., Tokyo, Japan. He was appointed a Research Associate and an Associated Professor to the Department of Environmental Technology and Urban Planning at Nagoya Institute of Technology in 1999 and 2007, respectively. Then, he was appointed an Associated Professor to the Department of Frontier Materials at Nagoya Institute of Technology. In 2012, he moved and was promoted to full professor to the Graduate School of Natural Science and Technology at Okayama University. Currently, he is the principal research scientist to the Advanced Nanocarbon Center for Composite Structural Materials (ANCS) at Okayama University under the Centers of Innovation (COI) program funded by the Ministry of Education, Culture, Sports, Science and Technology (MEXT). From June to November in 2005, he was with the University of Cambridge, as a Visiting Scientists, during which time he explored the metal filled carbon nanotubes. His research interests are fundamental physics, low-cost production and applications of various types of carbon nano materials, such as carbon nanotubes, graphene and carbon nanohorns. Dr. Hayashi is a member of the Japan Society of Applied Physics, IEEE and MRS.
