Research Scientist Position in Laboratory for Social Value Decision Making, RIKEN CBS-TOYOTA Collaboration Center, RIKEN Center for Brain Science

RIKEN Center for Brain Science (CBS) ( explores the mysteries of the brain—one of the ultimate frontiers in natural science—carrying out research at all levels, from cells to organisms and social systems, with the goal of returning those results to society. Brain science at RIKEN aims to develop domestic and international brain researchers by creating an environment that will integrate various intellectual disciplines and from that convergence find solutions that will ultimately benefit society in the realms of medicine, engineering, business, and education. In striving toward this goal, CBS (and its predecessor Brain Science Institute) has become a leading international center for brain research with a reputation for discovery, innovation, training, and globalization of the scientific enterprise.  

Laboratory for Social Value Decision Making ( in RIKEN Center for Brain Science is seeking a creative and motivated research scientist to address the following issues:

Societies around the world are now changing rapidly and in an accelerating pace. Research disciplines for studies of human being have not caught up with the rapid changes of the societies. To address these issues, our laboratory combines the research fields of decision science such as neuroeconomics, behavioral economics, psychology. In addition to these research fields of individual decision making, we will extend and connect principles of decision making to decision making at group and society levels with the aid of analysis techniques of big data, which are developed in new fields of collective behavior. Our research will bring about positive impacts to people in society by enhancing scientific understanding of humans and by creating sustainable designs of social systems. Through this exciting research endeavor, we create positive values for people in our global society.
