I am an M.S./Ph.D. student at Yonsei University, advised by Professor Seong Jae Hwang. I am currently a visiting researcher at Emory University, working with Professor Youngjoong Kwon.

My research interests lie in 3D vision, with a particular focus on working with 3D point clouds. I am especially drawn to enhancing the quality of 3D data from a low-level vision perspective and investigating encoding approaches that are well-suited to the unique characteristics of 3D data.

Looking for internship opportunities and open to research collaboration in 3D vision!
