Discrete Event Simulation Research Team
RIKEN Center for Computational Science
(Team Leader: Nobuyasu ITO)

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, and started its shared use since March, 2021.

The Discrete Event Simulation Research Team ("DESRT") performs cutting-edge research and development on discrete-event simulations and their wide applications, especially, simulations of social phenomena using agent-based models, and artificial-intelligence technologies towards so-called the "Society 5.0" and beyond.

Job title and job descriptions

Job title

Research Scientist or Postdoctoral Researcher: 1 position

Job description

Conduct research and development of agent-based models for social phenomena on massive parallel HPC systems and their applications together with applications of artificial intelligence under the guidance of PI Dr. Nobuyasu Ito. The main target is to develop models of social and economic phenomena and simulate them with supercomputer, using GPS data from mobile phones and firm- and business establishment-level trade data. Application of quantum information processing is also in scope.
If the candidate has the following experience, that will be considered.

• Developed social/economic models based on available real data
• Execute agent-based simulators, especially on supercomputer
• Analyzed large scale data
• Carried out economics, network science, or statistical physics related research

Qualifications

Applicants must have a Ph.D. or expect to receive a Ph.D. before the date of appointment. In general, those who earned a doctorate within the past 5 years will be appointed as Postdoctoral Researchers, and those who earned a doctorate more than 5 years ago will be appointed as Research Scientists. Experience of parallel programming, simulations and data-mining of social and economics phenomena, and artificial intelligence technologies is expected. Knowledge on quantum information processing is also expected.
