Friction at the Atomic Level

Motohisa Hirano was born in 1957 in Gamagori City, Aichi, Japan. Following his graduation from the Graduate School of Engineering, Nagoya University, in 1982, he joined Nippon Telegraph and Telephone Public Corporation in the same year. After working for Nippon Telegraph and Telephone Corporation (1985-2003) and serving as a professor at the Faculty of Engineering, Gifu University (2003-2014), he has been serving as a professor at the faculty of Science and Engineering, Hosei University, since 2014. He obtained doctoral degrees in engineering in 1989, from Nagoya University, and in science in 1998, from the University of Tokyo. Professor Hirano has authored over 200 scientific publications on engineering and science on the atomistics of friction and nanotribology.
