Jun Sugiyama was born in Nagoya, Japan in 1957. He graduated in 1979 B.S. Chemistry and in 1981 M.S. Applied Physics from Nagoya University. In 1981 he joined the sensor group of Toyota Central Research & Development Laboratories, Inc (TCRDL), where his work ranged from magnetic sensors to surface acoustic wave devices. He was requested to join at the new materials group of Superconductivity Research Laboratory (SRL) in Tokyo for 1989 — 1993. He completed his PhD thesis “Substitution effect on magnetism and superconductivity in Nd2CuO4″ in 1992 from Nagoya University.

During the stay in SRL, he initiated for using a muon-spin rotation and relaxation (+SR) technique at TRIUMF via Prof. Jess H. Brewer of Univ. of British Columbia to elucidate the microscopic magnetic nature of high-TC cuprates. He backed to the material division of TCRDL in 1993 and lead the research on cathode materials of Li-ion battery and thermoelectric materials. For the latter materials, he started an ambitious project with Jess in 2001 for clarifying the mechanism of thermoelectric properties of layered cobalt dioxides by +SR mainly at TRIUMF, one of the most intense muon sources in the world. Since then, he is the most powerful +SR user in the industrial world. He is a leader in the particle-beam analysis group of TCRDL, where he leads the research program for using both muon and neutron facilities all over the world to get a guiding principle for developing the materials potentially applicable for future automobiles. He was elected as a president of the Society of Muon and Meson Science of Japan for 2013 — 2017.
