Geon Lee

I am a Postdoctoral Researcher at the Information & Electronics Research Institute, KAIST, working with Prof. Kijung Shin at the Data Mining Lab. I received a Ph.D. degree in Artificial Intelligence at KAIST in 2026, advised by Prof. Kijung Shin, and won the Ph.D. Dissertation Award from the KAIST College of Engineering. I received my B.S. in Computer Science and Engineering from Sungkyunkwan University. During my Ph.D., I interned at Snap Research, NEC Labs America, and Amazon.

My research focuses on mining and learning on relational data (e.g., graphs, hypergraphs, and relational databases) as well as sequential data (e.g., time-series and user interaction sequences) and multi-modal data (e.g., text, visual, and tabular data). I am broadly interested in recommender systems, retrieval systems, and social network analysis. Recently, I have been interested in leveraging large language models (LLMs) to enhance learning and inference on relational and structured data, with a focus on developing frameworks that support complex and autonomous reasoning over real-world data.
