Job title and Job description

Job title, available positions

Postdoctoral Researcher 1 position

Job description

Mathematical modelling of circadian rhythms and/or virus infection dynamics.
The position is funded as part of a 5-year project until March 31, 2025 supported by Core Research for Evolutional Science and Technology (CREST), Japan Science and Technology Agency ( [Mathematical Information Platform]Creating information utilization platform by integrating mathematical and information sciences, and development to society ). With vast amounts of information now available on bio-molecules, we, mathematical modelling researchers are expected to integrate this information, to reveal new insights, and to derive solutions to important diseases. One of the goals of this project is to develop predictive and simple mathematical models describing either the circadian rhythms and/or virus infection dynamics, in collaboration with mathematicians, physicists, experimental biologists, and data scientists at RIKEN Center for Advanced Intelligent Project and other institutions. PI of the project is Prof Yoshinobu Kawahara (Institute of Mathematics for Industry, Kyushu University/RIKEN AIP), and its main collaborators are Profs Kenichi Bannai (Keio University/RIKEN AIP) and Hiroya Nakao (Tokyo Institute of Technology). Drs Gen Kurosawa and Catherine Beauchemin will jointly guide the selected candidate.


Applicants must have a Ph.D (or expected to hold a Ph.D prior to the start of employment) with a research background in theoretical sciences (mathematics, statistics, computational science, physics, or mathematical biology). Research experience in dynamical systems, bioinformatics, or time-series analysis is desirable.
