I recently completed my M.S. in Computer Science at Kyung Hee University and am continuing my research at the same lab as a Post-Master Researcher, advised by Prof. Jinwoo Choi. I am currently seeking PhD positions in the United States (Fall 2027).

My research centers on trustworthy multimodal video understanding across vision, language, and audio. Rather than a single technique, I'm drawn to the whole picture — how these models are trained, what they actually learn, and whether their reasoning is grounded, reliable, and interpretable. This thread runs across my work: diagnosing failure modes of Video-LLMs in DeltaDirect, concept-level explanation in DANCE (NeurIPS 2025 Spotlight), audio–visual reasoning in CA²ST (IEEE TPAMI 2026), and continual learning in ESSENTIAL (ICCV 2025 Highlight).

I am now moving toward Physical AI, studying video as the primary modality through which machines perceive, reason about, and eventually act in the physical world.

Before graduate school, I earned dual bachelor's degrees in Biomedical Engineering and Electronics Engineering. That interdisciplinary background — signal processing, embedded systems, and AI — still shapes how I approach research today.

I am always open to collaboration and discussion on computer vision, multimodal AI, and reliable video understanding. Feel free to reach out!
