Hello! I’m Euijun (E - June) Chung, a third-year Ph.D. student at Georgia Tech. My research focuses on GPU architecture, GPU security, and GPU simulations.

I am a member of the HPArch research group, where I am advised by Dr. Hyesoon Kim. Before I joined Georgia Tech, I received my B.S. in Electrical Engineering from KAIST in 2024.
