Hi! I'm Chunghyun Park (pronounced choong-hyun), a postdoc at POSTECH Institute of AI, working with Minsu Cho, who also advised my PhD. I work on 3D visual perception for systems that act in the physical world, and I'm now extending it to 3D world action models for robot manipulation. I interned at NVIDIA, received the Qualcomm Innovation Fellowship, and was selected for the CVPR 2026 Doctoral Consortium.
