I am a Ph.D. student in Network Convergence & Security Laboratory(MMLAB), Department of Computer Science and Engineering, Seoul National University. I am advised by Prof. Taekyoung (Ted) Kwon.

My research interests primarily lie in AI Security and Application Privacy. More specifically, I focus on security in distributed learning environments, as well as privacy protection within network and web environments.

In addition to security research, I have a strong passion for hacking and CTFs, with a primary focus on web hacking. I am currently an active member of RubiyaLab, participating in various CTF competitions. I also serve as a subcommittee member for the Hacking Organization Research Group at the Korean National Police Agency
