About

I am a second-year Ph.D. student at KAIST, advised by Prof. Jinwoo Shin, and a Research Intern at NAVER Cloud. My research interests lie in building intelligence that is self-aware and safe. To this end, I focus on developing Large Language Models (LLMs) that can reason, make decisions (i.e., exhibit agentic behaviors), and ensure safety. I am also broadly interested in the continual pretraining of LLMs and their multilingual capabilities.

Topics of interest: LLM, LLM Reasoning, LLM-based Agents, LLM Safety
