Interdisciplinary Theoretical and Mathematical Sciences Program (iTHEMS) is an international research program at RIKEN. It facilitates close collaborations among researchers from different disciplines in theoretical, mathematical and computational sciences. The ultimate goal of iTHEMS is to unravel the mystery of the Universe, matter, and life, as well as to solve key problems in modern society through interdisciplinary approaches.

Special Lecture

Tetsuo Hatsuda × Yoshinori Ohsumi × Sayaka Oki Online Discussion: "The Usefulness of 'Useless' Knowledge" Presented by iTHEMS & academist

August 22 at 13:00 - 15:30, 2020

Dr. Tetsuo Hatsuda (Program Director, iTHEMS)
Prof. Yoshinori Ohsumi (Cell Biology Center, Institute of Innovative Research, Tokyo Institute of Technology)
Prof. Sayaka Sayaka (Professor (History of science and technology), Graduate School of Economics Department of Socio-Economic System, Nagoya University)

学問の世界で大切なのは、研究者の「なぜ」「不思議だな」という好奇心です。研究者は自らの好奇心をもとに想像力を膨らませ、さまざまな仮説を立て、それを実験、観測、調査で検証し、最終的には理論的に体系づけていきます。このような基礎研究で得られた知識は、私たちの生活に直接「役に立つ」ものではありません。しかし、5年、10年といった期間ではなく、100年、1000年単位で考えると、基礎研究は確実に世の中の役...more

Seeking a Research Scientist or Postdoctoral Researcher (CPR-PS1903) *Prediction Science

Deadline: August 9, 2020

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.

Seeking a Postdoctoral Researcher or Research Scientist (W20014) *particle physics and quantum gravity

Deadline: October 1, 2020

iTHEMS is seeking postdoctoral researcher(s)/research scientist(s) in the field of particle physics and quantum gravity. Successful applicant(s) are expected not only to pursue top-level researches in their own field but also to lead interdisciplinary collaborations among different fields such as mathematics, physics, chemistry, life sciences, engineering, computational sciences, information sciences, and social sciences, under the concept of iTHEMS. In particular, we welcome applications from young researchers who are interested in exploring the properties of spacetime and matter under extreme conditions such as black holes and the early universe, as well as the theory of quantum gravity in a broader sense.

Seeking a Postdoctoral Researcher or Research Scientist (W20001) *condensed matter theory

Deadline: October 31, 2020

iTHEMS is seeking postdoctoral researcher(s)/research scientist(s) in theoretical condensed matter physics. Successful applicant(s) are expected not only to pursue top-level researches in their own field but also to lead interdisciplinary collaborations among different fields such as mathematics, physics, chemistry, life sciences, engineering, computational sciences, information sciences, and social sciences, under the concept of iTHEMS. This time, we encourage junior applicants who have high research potential in theoretical studies of topological states of matter, Majorana modes, topological quantum computing, mathematical physics, non-Hermitian systems, and related fields.

Seeking a Postdoctoral Researcher or Research Scientist (W20002) *machine learning

Deadline: October 31, 2020

iTHEMS is seeking postdoctoral researcher(s)/research scientist(s) in the field of machine learning. Successful applicant(s) are expected not only to pursue top-level researches in their own field but also to lead interdisciplinary collaborations among different fields such as mathematics, physics, chemistry, life sciences, engineering, computational sciences, information sciences, and social sciences, under the concept of iTHEMS. This time, we encourage junior applicants who have high research potential in theories and applications of machine learning.
