Seeking a Research Scientist or a Postdoctoral Researcher (R-CCS2106)
The RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is an international hub for computational science that promotes “science of computing, by computing, and for computing.” R-CSS positions the technology in which RIKEN has strengths (R-CCS technology) and the software developed by RIKEN that contributes to science, technology, industry, and society (R-CCS software) as its “core competence in computational science driving science as a whole.” R-CCS aims to develop these technologies, disseminate them domestically and internationally, and produce results. In addition, R-CCS is utilizing its expertise to operate the supercomputer “Fugaku” which was developed as a national project in accordance with Japanese laws and regulations.
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
Research Scientist or Postdoctoral Researcher: 1 position
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
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.
