In social science, there are theoretical and empirical fields. Our laboratory uses mathematical models such as “game theory” and “network science” for building up theories, and mainly statistical surveys for verification. We also place an importance on social science viewpoints in addition to the mathematical methods. Students decide their topic of research by considering interests and curiosity of their own. The laboratory is characterized by the use of twitters, cloud funding and big data, the atmosphere to give students take up wide-ranging subjects and personal relationships that allow an “exit selection.”
