M.S. student, Yonsei University

I am an M.S. student at Yonsei University advised by Youngjae Yu and Jongmin Lee. Concurrently, I am a research scientist intern at the Artificial Intelligence and Robotics Institute in KIST. I previously researched at LG AI ResearchNaver Cloud and maumAI. Before the M.S. degree program, I received a B.A. in Applied Statistics and a B.S. in Computer Science & Engineering from Yonsei University. My research aims to find autonomous embodied AI capable of accumulating knowledge from multimodal real-world experience without continual human supervision. I strive to achieve this goal by a scalable yet simple approach. I am currently interested in multimodal generative models, AI alignment for Robotics, and parameterized memory for continual learning.

🙌 Looking for Ph.D. programs! 🙌
