Hello! I am currently a M.S. student at the Language & AGI Lab at Yonsei University, advised by Prof. Jinyoung Yeo.
My research interests are centered around establishing science on LLMs' generation behavior.
Building on this foundation, I aim to continuously expand LLMs’ potential towards generalist agents that understand world knowledge and assist users regardless of situation.
To achieve this vision, my research focuses on (1) analyzing LLMs in diverse real-world contexts and (2) enhancing their capabilities based on these analyses.
My ultimate research goal is to design systems that enhance people’s quality of life, in a reliable and responsible manner.
Below are some keywords of my recent research interests:
