πŸ‘¨β€πŸŽ“ About Me

I'm a Ph.D. student in Computer Science at Hanyang University, South Korea, where I am fortunate to be advised by Prof. Tae Hyun Kim.

My research focuses on developing reliable and efficient restoration systems for real-world images and videos. Broadly, my work lies at the intersection of computer vision, machine learning, and generative modeling.

I design both dataset synthesis frameworks and restoration models for tasks such as video stabilization, image denoising, and super-resolution. A key emphasis of my research is ensuring robustness under practical constraints, including test-time adaptation, continuous degradations, diverse unseen noise patterns.
