I am a postdoctoral researcher at the Division of Decision and Control Systems, School of Electrical Engineering and Computer Science (EECS), KTH Royal Institute of Technology, with supervisor Prof. Karl Henrik Johansson. I received my B.E., M.E., and Ph.D. degrees from Keio University in 2016, 2018, and 2024, respectively, with supervisor Prof. Toru Namerikawa. My research centers around theoretical analysis to develop secure and resilient control systems, with main interests in the secure state estimation problem and vulnerability analysis in control systems.

Previously, I worked at Mitsubishi Research Institute from 2018 to 2025 as a consultant, where I mainly engaged in research and study of cybersecurity policy in Japan. Also, I was a visiting researcher at Keio University from 2024 to 2025.
