About Me
I am currently a PhD student at Jeonbuk National University, advised by Prof. Sang Jun Lee. My research focuses on developing vision systems that address real-world challenges in remote physiological signal estimation, medical image analysis, and 3D reconstruction, with an emphasis on robust deep learning models for unconstrained environments.
Recently, I've been advancing camera-based remote photoplethysmography (rPPG) for reliable operation in unconstrained, in-the-wild conditions.
My long-term goal is to discover and precisely define practical problems, and to develop domain-appropriate AI models that translate into deployable, real-world solutions.
