AI researcher working on Large Language Models, Graph Neural Networks, and Retrieval-Augmented Generation — with a focus on structured reasoning and scientific knowledge systems.

About

I am a Post-Master's Researcher at the Korea Atomic Energy Research Institute (KAERI), where I conduct research at the intersection of artificial intelligence and scientific domains.

I earned my M.S. in Computer Engineering (AI Major) from Chungnam National University (CNU) in February 2026, where I was advised by Prof. Sungsu Lim at the Data Intelligence Laboratory (DILAB). My undergraduate degree is in Mathematics, also from CNU.

My research explores how structured knowledge — graphs, citations, and retrieved context — can be combined with large language models to enable more reliable reasoning. As first or co-first author, I have published at PAKDD and a CIKM Workshop, and in the SCIE journal Applied Sciences.
