Seokjun Choi

I am a Ph.D. student in the Computer Graphics Lab at POSTECH, advised by Prof. Seung-Hwan Baek.

My research explores computational methods for understanding and interacting with the physical world through appearance. I develop practical imaging systems and algorithms for 3D reconstruction, inverse rendering, and polarimetric appearance acquisition.

My current work extends these directions toward appearance fabrication and visuo-tactile sensing, connecting optical appearance with physical materials and interactions.
