Seoul National University

I am a postdoctoral researcher at the Seoul National University (SNU) Institute of Computer Technology, currently serving my mandatory military service as expert research personnel. I earned my Ph.D. from Security Optimization Lab (SOR Lab) in the Department of ECE at SNU, under the supervision of Professor Yunheung Paek. My current research interests include, but are not limited to: systems security, autonomous vehicle security, confidential computing, and on-device AI security.
