Seeking a Research Scientist or Postdoctoral Researcher (CPR-PS2203)


Prediction Science Laboratory
RIKEN Cluster for Pioneering Research
(Laboratory head: Takemasa Miyoshi)

Pioneering Project (FY2020-FY2024)

RIKEN started a new pioneering project titled “Prediction for Science” in April 2020 for 5 years. For the concept of Prediction Science, refer to the next section “Research field”. Researchers under this call will work together with various laboratories in theory and applications and will bring synergy and fusion among different areas, so that we pioneer a general theory of prediction, the first step toward the whole new world of “Prediction Science”. To achieve the ambitious goal, the researchers under this call will spend an extended period for several months or longer in some of the participating laboratories as shown below and will work on the synergy and fusion among theory and a few application areas. We expect that the researchers under this call stay at different locations in Japan for an extended period.

List of participating laboratories:

Research field

The Prediction Science Laboratory pioneers a new science of prediction as the 5th paradigm fusing the computational science (3rd science) and the data science (4th science) through tight collaborations with the sister laboratory Data Assimilation Research Team, RIKEN Center for Computational Science, as well as other collaborators within and beyond RIKEN. Weather prediction is probably the most successful example of prediction by modern science by putting together human knowledge of different areas such as information and communications technology, supercomputing, mathematical modeling and simulation, sensing, and applied mathematics of dynamical systems and uncertainty quantification (UQ). Data assimilation integrates simulation and real-world data and plays a central role in numerical weather prediction. Various types of simulations beyond weather became more and more realistic due to advances of high-performance computation technology. In addition, information revolution brought the current era of Big Data and IoT (Internet of Things). The Prediction Science Laboratory will pioneer the new “Prediction Science,” the 5th science fusing the computational science and the data science, and will bring the success of weather prediction to various fields.

Job title and job descriptions

Job title

Research Scientist or Postdoctoral Researcher: one position

Postdoctoral Researcher is defined as those with a doctoral degree of 5 years or less.
Research Scientist is defined as those with a doctoral degree more than 5 years.

Job description

The successful candidate for Pioneering Project "Prediction for Science" (FY2020-FY2024) will conduct research to pioneer the new “Prediction Science” and to develop the general theory of prediction. The specific research examples include application of data assimilation to new areas, generalization of data assimilation among multiple areas, and applied mathematics of uncertainty quantification (UQ) and topological data analysis. In this project, we collaborate with laboratories in environmental science fields (weather, climate, marine ecology) and life science fields (cell biology, medicine) for specific problems for prediction, and develop the general theory of prediction in collaboration with pure and applied mathematicians and AI and statistical scientists. We will develop new mathematical theories and methods which will serve as a basis for the new “Prediction Science”, apply these new theories and methods to various application areas, and bring virtuous feedback between theoretical developments and application studies.


The candidate should possess a doctoral degree in a related field of prediction science and research experience.

Salary and benefits

  • 1.A one-year fixed-term employment contract, renewable based on evaluation, up to the end of March 2025 from date of hire.
  • 2.RIKEN may adjust the above maximum period of renewability based on a) the employee’s abilities, workload at the time of contract completion, performance and work attitude and b) the continuation of the employee’s center, laboratory or project and RIKEN’s management situation and budget at the time. In principle, employment contracts will not be renewed for individuals older than 65 years.

In principle, the first two months of employment is considered a trial period.
Salary will be an annual salary based on experience, ability, and performance, and will consist of a base salary and a variable salary. The variable salary will be determined each fiscal year based on experience, ability, and performance. As of April 1, 2023, the monthly base salary is 350,300 JPY (Research Scientist) and 295,100 JPY (Postdoctoral researcher) . The monthly base salary and variable salary are subject to change due to amendments to RIKEN regulations. Discretionary work, commuting and housing allowances will be provided. Social insurance will be applied.
The approximate amount of annual salary at the time of employment:
In the case of a special researcher with experience, ability, and achievement of about one year after completion of the doctoral degree, the monthly salary at the time of employment including discretionary allowance will be about 400,000 yen, and in the case of a researcher with experience, ability, and achievement of about six years after completion of the doctoral degree, it will be about 600,000 yen.
Mandatory membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai).
This position falls under the specialized duties discretionary work system; one working day will be calculated as 7 hours and 30 minutes.
Days off include public holidays, New Year's holidays (Dec. 29 - Jan 3), and RIKEN Foundation Day.
Paid leave includes annual paid leave (up to 20 days depending on the month of employment), special paid leave (childcare, family nursing care, etc.), and work life balance holidays (up to 7 days depending on the month of employment).
There are also additional leave systems such as maternity leave, childcare leave, and family nursing care leave.
