Research Outline

With the digitalization of society by ICT and IoT, and the socialization of the Web, people’s behavior is now being digitally recorded and stored. In our lab, we analyze and model such large-scale data on human behavior (big data) by means of computational social science, applying the obtained knowledge and insights for social innovation and value creation. Computational social science is a social science in the digital age; an interdisciplinary field that quantitatively studies individuals, groups, and societies with unprecedented resolution and scale by making full use of (1) big data analysis; (2) experiments and surveys using digital tools; (3) modeling of social phenomena. In particular, we are exploring the principles and techniques for dynamically maintaining the diversity and reliability of information in social networks. In Society 5.0 where people, things, and information are interconnected without barriers between online (the Internet) and offline (the real world), such principles and technologies will open up new possibilities of social capital as a source of value creation, and are expected to be applied to various social innovations.

  • We collaboratively work on projects related to computational social science.

  • In addition to daily discussions, a seminar, a journal club, and a study meeting are held once a week.

  • We actively present our research results in internal/international conferences and publish them as papers in journals.

  • We welcome motivated students who tackle research seriously. If you are interested in conducting graduation study or becoming a master's or doctoral student in this lab, please contact Prof. Sasahara. We accept requests for lab visits and online interviews.

  • International students are required to have Japanese language skills, as the lab meeting is conducted in Japanese.

  • In case of research students, we can only accept government-sponsored exchange students due to limitations of lab space.
