Juhee Kim
Postdoctoral researcher, CompSec Lab, Seoul National University.
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 low-level operating systems and hardware, with a focus on identifying new attacks and designing practical defenses. I am currently working on securing LLM-based agent systems from a system security perspective.
