INTERVIEW
Unique Appeal of the Social Data Science Program
The variety of faculty members is an attractive point of SDS. It is rare to find such a faculty of various members majoring in social sciences, statistics, and informatics/AI. Students can take many interesting subjects and discuss leading topics with faculty members. Students are also encouraged to take subjects from other faculties to expand their horizons. To improve our society through data science techniques, skills to find and formulate social challenges are needed. The curriculum at SDS is designed to cultivate such a viewpoint. SDS is unique in that students can learn not only the fundamentals of data science but also how to apply them to practical social challenges.
Innovative education and research encouraged in the Social Data Science Program
My research fields are information networks and distributed systems. I am especially interested in techniques that enable cooperation among a large number of computers. While valuing the fundamental research perspective that only an academic institution can provide, I would like to expand my efforts based on social challenges through research collaborations with industry. I hope that students will acquire high expertise through the SDS curriculum. Of course, the substance of the expertise is important, but it is also highly valued to learn how to deepen the expertise. We live in an era that is changing rapidly, and some parts of the knowledge we acquire may become outdated soon. However, the skills to learn and apply new things will not be outdated. I would like to provide a meaningful place where students can cultivate such skills.

MESSAGE
I hope that students will experience a lot of trial and error, not only in their studies but also in their student life.
As a faculty member, I would like to provide an environment where students can have various opportunities to do so.
Through such trial and error, please ask yourself what you think about the ideal society with data science technology.
Since SDS has an interdisciplinary curriculum, the students, faculty, and staff have a wide variety of backgrounds.
I am looking forward to discussing various things with such diverse students at SDS.

RESEARCH
My primary research fields are information networks and distributed systems. I am interested in techniques that enable cooperation among many computers, especially decentralized systems like blockchain. Decentralized systems do not have a central server to manage the entire system; instead, each computer constituting the system behaves autonomously. Since each computer does not have global information (e.g., the total number of computers in the system), it may behave inefficiently. One of my research topics is developing algorithms that allow such a group of computers, each with limited information, to cooperate efficiently. Besides, I am working on load-balancing techniques to enable large-scale IoT data collection, wireless mesh networks for disaster prevention, and blockchain-based smart cities.
