I am an associate professor at the University of Electro-Communications (UEC). Besides, I concurrently serve as:
Invited 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.
