About Me

Research Interests: LLM Reasoning & Reliability, Agentic AI, Self-Evolving Memory, LLM Applications

I am an undergraduate student in the School of Computing at KAIST, currently working as an undergraduate researcher at the MLAI Lab in KAIST Graduate School of AI.

My long-term goal is to build AI systems that go beyond surface-level language processing: systems that can genuinely understand, retain, and use context in meaningful ways. My research aims to make large language models more reliable and adaptive when they reason over information that changes across time and context.
