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

I am broadly interested in building trustworthy and safe AI that can operate reliably under real-world conditions. In parallel, I am also interested in making large model architectures more adaptable and efficient.

My recent research interests include the following topics:

• Trustworthy and Safe AI
• Efficient Architecture for Large Models
