Undergraduate, Pukyong National University

I am an undergraduate student in Computer Engineering at Pukyong National University and currently a research intern in the Computer Vision and Signal Processing Lab (CVSP Lab) at Pusan National University.

My research focuses on understanding the internal representations and information-processing mechanisms of Multimodal Large Language Models, and leveraging these insights to improve inference efficiency and mitigate hallucinations.

More recently, I have been interested in extending this perspective to Multi-Agent Systems.
