I am 2nd year M.S student in CVLAB@KAIST AI under the advisement of Prof. Seungryong Kim.

My research interest lies in understanding real world at multiple levels through the visual information, with the goal of solving practical problems. In particular, my current research focuses on segmentation and multimodal large language models (MLLMs).

Before joining KAIST, I received my B.S in Life Science from Korea University, where I was particularly fascinated by neuroscience. I remain deeply intrigued by the analogies between the human neurobiological system and artificial intelligence, and I look forward to the synergy they will continue to create.
