Sihyun Yu

I am a final-year Ph.D. candidate at KAIST, advised by Jinwoo Shin. I also work closely with Saining Xie at NYU. During my Ph.D., I interned at Google Research/DeepMind and NVIDIA Research to design efficient video generation models. I also collaborated with Kihyuk Sohn through the university relations program at Google Research.

I am broadly interested in a range of problems in computer vision. In particular, my research focuses on the intersection of visual representation learning and generative modeling towards unified, human-like vision models capable of both creating and understanding complex visual worlds. I am also interested in AI4Science and have contributed to several related projects.
