Research Field

Societies around the world are now changing rapidly and in accelerating speeds. 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 the research fields of individual decision making, we will extend and connect principles of decision making, which are found in experimental rooms, 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 such as computational social science. Our research will bring about positive impacts to people in society by humanizing practices of work environments and by creating sustainable designs of social systems. We welcome eager and ambitious participants in this exciting research endeavor to create positive values for people in our global society.

Job description

Field Study of Decision Making with Data Science Approach
Development of techniques of collecting and analyzing data have made available previously unimaginable amount and diversity of data about human behavior. Yet, efforts to formulate theories and hypotheses to explain these large-scale data of human decision making have not caught up with the speed and scale of data collection. People who are eager to fill this gap between theory and practices of decision making in large-scale environments are encouraged to apply. We welcome applications from people who have academic and industrial experiences of (preferred, but not exclusive) marketing, network science, people analytics with the use of big data about individual and collective decision making.


A candidate for research scientist needs to have Ph.D.
(D.Phil) or is expected to have obtained Ph.D. (D.Phil) before the date of assuming the position. We also welcome candidates who have relevant experiences in collection and analysis of big data about individual and collective decision making. In these cases, we do not require Ph.D. and accept talented people as technical staff. With a diverse team and extended networks within and across organizations, communication skill is important for this position. We also consider flexibility in work styles in working time.
