Seeking a Research Scientist or Postdoctoral Researcher (CPR-PS2002)


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.

Research Scientist or Postdoctoral Researcher: a few positions

Job description

The successful candidate 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. Experience as or equivalent to a university professor will be advantageous.
