Bio

Received his PhD from the Graduate School of Systems and Information Engineering, University of Tsukuba in March 2006. From 2006, he became engaged in research and development of knowledge cluster systems at the National Institute of Information and Communications Technology (NICT). In 2014, he became associate professor and senior research fellow at the Center for Global Communications, International University of Japan, engaged in research and development of mining and data mining methods. In April 2018, he joined the Faculty of Engineering, Musashino University, as associate professor, and has been an associate professor in the university’s Faculty of Data Science since April 2019. He has also been a member of the Study Group on the Utilization of Information in the Distribution and Logistics Field, Ministry of Economy, Trade, and Industry (2015–16); a member of the study group on the impact assessment of ICT intelligent systems, Ministry of Internal Affairs and Communications (2016); and a member of the AI Network Society Promotion Council, Ministry of Internal Affairs and Communications (2016–).
