Research Summary

Masayuki Ihara (Ph.D.)

The data science design team conducts research on methodology of designing person-centered services with design thinking and data science. We contribute to solve social issues by utilizing both science data that professionals have and field data in citizens’ living environments at each design step; empathizing with users, defining a problem and ideation of the solution. Our goal is to realize citizen science in which not only professionals but also citizens can join in experiencing a science event or creating a service with data science as well as to construct the open system of effective collection, maintenance and utilization of data.
