I am a 1st-year Ph.D. student in Computer Science at UNC Chapel Hill, advised by Prof. Mohit Bansal. I received my M.S. from Yonsei University, where I was advised by Prof. Bumsub Ham, and was also affiliated with Kyung Hee University, where I was co-advised by Prof. Suhyun Kim, formerly at KIST.

I am broadly interested in building trustworthy and safe AI that can operate reliably under real-world conditions. If you have any questions, feel free to contact me!
