About Me

Hi! I’m Junhyeok Lee, an M.S. student in Artificial Intelligence at POSTECH and a member of the Efficient Learning Lab (EffL), advised by Prof. Jaeho Lee.

My research interests broadly lie in Efficient AI, with a particular focus on efficient long-term visual memory for video understanding. Specifically, I investigate how video-LLMs can efficiently retain and leverage visual information over long temporal contexts.
