About Me

Hi, my name’s Taesung and I’m a fourth-year Ph.D. candidate in KAIST, advised by Prof. Jong Chul Ye and Prof. Mooseok Jang. During my Ph.D., I was a research intern at Disney Research Studios in Zurich. My research focuses on improving the conditional generative process by controlling the diffusion dynamics and designing efficient architectures. In parallel, I investigate how temporal correlations can be exploited to enhance generative modeling and inverse problem solving.

My recent research spans three key areas, including but not limited to:

  • Generative Models: Diffusion models for video inverse problems, video frame interpolation, and image generation/editing.

  • Efficient Generative Modeling: Designing efficient architectures and training/sampling frameworks for diffusion models.

  • Physics-Based Vision and Medical Imaging: Applications to physical sciences (e.g., inverse scattering in optics) and medical imaging.
