Junyi Zhang 章俊一

Hi! I am a PhD student at UC Berkeley, advised by Prof. Trevor Darrell. Previously, I obtained my B.Eng. (Honors) in Computer Science from Shanghai Jiao Tong University (SJTU). I am currently a research intern at Physical Intelligence, and I have also stayed at Google DeepMind and Microsoft Research Asia.

My research interests mainly lie in computer vision, deep generative models, 4D, and robotics.

Misc.

I am a cinephile. My favorite directors include Martin Scorsese, Theodoros Angelopoulos, Leos Carax, Jean-Luc Godard, Paul Thomas Anderson, and many more. You can find a list of some of my favorite films here. I was the VP of the student group 'No. 800 Film Society' and hosted several film salons and curated several screening series. I also write reviews on films, books, and games (in Chinese) on Douban.
