Satoshi Matsuoka
Director, RIKEN Center for Computational Science

Satoshi Matsuoka had been a Full Professor at the Global Scientific Information and Computing Center (GSIC), the Tokyo Institute of Technology since 2001, and the director of the joint AIST-Tokyo Tech. Real World Big Data Computing Open Innovation Laboratory (RWBC-OIL) since 2017, and will become a Specially Appointed Professor at Tokyo Tech starting 2018 along with his directorship at R-CCS. He received his Ph. D. from the University of Tokyo in 1993.

He has been the leader of the TSUBAME series of supercomputers that have won many accolades such as world #1 in power-efficient computing. He also leads various major supercomputing research projects in areas such as parallel algorithms and programming, resilience, green computing, and convergence of big data/AI with HPC. He has been a major driving force behind the development of the next-generation flagship supercomputer of Japan, the supercomputer Fugaku. In June 2020 Fugaku won the first place in four major rankings of supercomputer performance, Top500, HPCG, HPL-AI, and Graph500.

He has written over 500 articles according to Google Scholar, and chaired numerous ACM/IEEE conferences, including the Program Chair at the ACM/IEEE Supercomputing Conference (SC13) in 2013. He is a Fellow of the ACM and European ISC, and has won many awards, including the JSPS Prize from the Japan Society for Promotion of Science in 2006, presented by his Highness Prince Akishino; the ACM Gordon Bell Prize in 2011; the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology in 2012; the 2014 IEEE-CS Sidney Fernbach Memorial Award, the highest prestige in the field of HPC; HPDC 2018 Achievement Award from ACM; and recently SC Asia 2019 HPC Leadership Award.

Mitsuhisa Sato
Deputy Director, RIKEN Center for Computational Science

Mitsuhisa Sato received his undergraduate degree in 1982 from the Department of Information Science, School of Science, the University of Tokyo, and continued his study at the Graduate School of Science, the University of Tokyo, after which he joined the GOTO Quantum Magneto Flux Logic Project at the Research Development Corporation of Japan. In 1991 he joined the Electrotechnical Laboratory of the Ministry of International Trade and Industry (MITI), and from 1996 headed the Parallel and Distributed System Performance Laboratory of the Real World Computing Partnership. From 2001 to 2015 he served as Professor in the Graduate School of Systems and Information Engineering, University of Tsukuba, and Director of the Center for Computational Sciences from 2007 to 2012.

At the RIKEN Advanced Institute for Computational Science (AICS) he led the Programming Environment Research Team from 2010, and since 2014 has been appointed to deputy project leader for the Flagship 2020 Project at AICS (now R-CCS). He serves as Deputy Director of R-CCS since fiscal year 2018. He is also Professor (Cooperative Graduate School Program), Tsukuba University; Professor Emeritus, the University of Tsukuba; and Fellow of the Information Processing Society of Japan. His research interests include: parallel processing architecture; programming models, languages, and compilers; computer performance evaluation technology.

Masanori Shinano
Deputy Director, RIKEN Center for Computational Science

After earning his undergraduate degree from the Department of Mechanical Sciences and Engineering at the Tokyo Institute of Technology, Masanori Shinano went on to complete a master’s degree in nuclear engineering at the same institute’s Graduate School of Engineering in 1988. He then joined the Science and Technology Agency (now MEXT, the Ministry of Education, Culture, Sports, Science and Technology).

Since then, he has worked in policy planning and project promotion for big science fields such as marine science and technology and space development, in addition to providing support to academic activities at Science Council of Japan (SCJ) and national universities.
He has also served in organizational management at the National Museum of Emerging Science and Innovation, the Japan Agency for Medical Research and Development (AMED), and MEXT, and taken on a variety of other roles in government and related agencies including the Cabinet Office, the Ministry of Economy, Trade and Industry (METI), the Cabinet Satellite Intelligence Center (CSICE), the Secretariat of the Nuclear Regulation Authority (NRA), Shinshu University, and RIKEN. He was appointed to the current position in April 2022.
