I am a Ph.D. student in Computer Science at Yonsei University, advised by Professor Seong Jae Hwang. I am also an external collaborator with the Emory Vision and Graphics Lab at Emory University, working with Professor Youngjoong Kwon, where I previously spent time as a visiting researcher (Feb 2026 - Jun 2026).

My research interests lie in 3D vision (point cloud processing, 3D reconstruction, and point cloud restoration) and human-centric vision (human performance capture, novel-view human animation, 3D human pose analysis, and video-based inverse dynamics).

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