Seeking a Research Scientist or Postdoctoral (R-CCS-P1906)


Computational Disaster Mitigation and Reduction Research Team
RIKEN Center for Computational Science
(Team Leader: Satoru Oishi)

Research field

RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is an international research center in high performance computing and computational science in Japan. Our objectives are to investigate “the Science of (high performance) computing, by computing, and for computing”, to research and develop our technologies (R-CCS technology) and software (R-CCS software), which we consider our core competence, in order to produce world-leading scientific and engineering results for use in Japan as well as globally.

Also, R-CCS started operating Japan’s national flagship supercomputer Fugaku, as a shared national facility to support a wide range of research activities since 2021.

Computational disaster mitigation and reduction research team is aimed at advancing large-scale numerical simulations of extreme climate phenomena such as earthquakes, tsunamis, heavy rainfall, river disasters and landslides, and their combined disasters targeting Kobe City and other urban areas in Hyogo Prefectures.

Besides the development of a sophisticated urban structure model and the development of new numerical codes, the team seeks to be a bridge between Science and Local Government for disaster mitigation and reduction.
