Hello, my name is Juhee Kim, and I am a postdoctoral researcher at CompSec Lab, Department of Electrical and Computer Engineering, Seoul National University. I received my Ph.D. from the same research group, advised by Byoungyoung Lee.
My research background spans system security from high-level user programs to hardware side-channels, with a focus on identifying new attacks and designing practical defenses. I am currently working on the security of LLM-based agent systems.
