Junseo Bang

Hi! I am a Ph.D. student in Electrical and Computer Engineering at Seoul National University, where I also received my B.S. degree. I am advised by Prof. Se Young Chun at the Intelligent Computational Imaging Lab (ICL). My research focuses on solving inverse problems and controlled image generation with generative models (e.g. diffusion, flows).

Prior to ICL, I was advised by Prof. Byoungho Lee and Prof. Yoonchan Jeong at the Optical Engineering and Quantum Electronics Lab, where I explored advanced imaging systems and light modulation using nanophotonic and metasurface technologies.

💡 I will bridge these two domains — from optical imaging system design to AI-driven signal processing and generative modeling — to develop next-generation intelligent imaging systems that integrate physics and machine intelligence.
