Bio

I am Juil Koo, a fourth-year PhD student in the KAIST Visual AI Group, led by Prof. Minhyuk Sung. In summer 2024, I interned at Adobe Research.

My research interests lie in generative modeling and reasoning in vision, aiming to build AI systems that can assist or automate human workflows via visual understanding and generation. Prior to this, I mainly worked on the intersection between 3D geometry and language. I aim to address practical problems through theoretical insights.

My Erdős number is 3 (Juil Koo → Leonidas Guibas → Frances Yao → Paul Erdős).
