Jihoon Chung

I am a Ph.D. candidate in Computer Science at Princeton University, advised by Olga Russakovsky in the Princeton Visual AI Lab. I received my M.Phil. and B.Eng. in Computer Science from HKUST, advised by Chi-Keung Tang.

My research focuses on computer vision, with interests in video understanding, action recognition, and vision-language models.
