About

I am an M.S. student at KAIST AI, advised by Prof. Kijung Shin in the Data Mining Lab. Prior to this, I received my B.S. in Industrial Engineering and Computer Science from Yonsei University.

My research focuses on building practical and reliable AI systems capable of effectively retrieving, reasoning with, and leveraging structured knowledge. Currently, I am particularly interested in structured retrieval, agentic systems, and knowledge-intensive reasoning.
