Katsuya Shimizu is a Professor in the Graduate School of Engineering Science, Osaka University, and also a group leader of the high-pressure team of KYOKUGEN, Center for Quantum Science and Technology under Extreme Conditions, Osaka University.

He is working on material sciences at extreme conditions, frontier studies, and developments for the pressure-induced novel properties such as superconductivity, magnetism, and metallization of simple systems. The unique experimental technique is now essential and widely spreading to the community of materials science for future applications.

Katsuya achieved his PhD at the Graduate School of Engineering Science, Osaka University, and worked as a Research Fellow of the Japan Society for the Promotion of Science for Young Scientists (1995.4~1997.3), Research Assistant, Division of Materials Physics, Graduate School of Engineering Science, Osaka University (1997.4~2002.3), Lecturer (2003.4~2014.3), then current position (2003.4~).
