I am an assistant professor at the University of Electro-Communications (UEC), and also working as Excellent Young Researcher, LEADER, MEXT. Besides, I concurrently serve as:
Invited Advisor at Security Fundamental Laboratory, Cybersecurity Research Institute, NICT;
Collaborative Researcher at Advanced Cryptography Research Team, CPSEC, AIST;
Research Fellow at Japan Datacom Co., Ltd.

My research area is cryptography, especially public-key crypto and information-theoretic crypto. In 2016, I got my Ph.D. in information science at Yokohama National University, Japan, under the supervision of Prof. Junji Shikata.

I’m currently serving as General Co-Chair of PKC 2022. We’re currently watching the coronavirus situation and working on finding a better PKC conference style. I’m looking forward to seeing you in Yokohama, Japan, hopefully.
