I am a M.S. student at Yonsei University in the CVLab, advised by Prof. Bumsub Ham, and also affiliated with KDST at Kyung Hee University (formerly at KIST), co-advised by Prof. Suhyun Kim.

I am broadly interested in building trustworthy and safe AI systems that can operate reliably under real-world conditions. In parallel, I am also interested in making large models more adaptable and efficient, while preserving their core capabilities.

My recent research interests include the following topics:

• Trustworthy and Safe AI
• Efficient Training and Inference for Large Models
