Hello, my name is Juhee Kim, and I am a PhD student at CompSec Lab, Department of Electrical and Computer Engineering, Seoul National University. I am advised by Byoungyoung Lee.
My research interests span a broad spectrum of software security issues and finding practical solutions. My recent research explores ARM’s Memory Tagging Extension (MTE), looking at how it can protect the systems and how it can be bypassed. I am also interested in the security of LLM agents and GPU/ML systems.
I am looking for a summer internship in 2025. Please feel free to contact me if you are interested in working with me!
