About Me
I am Chenyu Jiang (江宸宇). I am currently working at ByteDance Seed, building systems and infrastructure for video generation models. I received my Ph.D. in Computer Science from The University of Hong Kong, advised by Prof. Chuan Wu, in 2025, and my B.Sc. in Computer Science from The Chinese University of Hong Kong in 2020. My Ph.D. research focused on optimizing distributed LLM training systems.
In my spare time, I like to take photos. You can find some of them here.
