Hi! I am a Ph.D. candidate at Seoul National University since 2023.
I am currently advised by Prof. Jung Ho Ahn and a member of
SCALE Lab ↗. Before pursuing Ph.D., I received a B.S. in Electrical and Electronic Engineering from Korea University in 2023.
My research primarily focuses on high performance memory system for LLMs and DRAM reliability & security. For further information, please refer to my CV.
