Jiaxin Ge

About

I am a Ph.D. student in Computer Science at UC Berkeley, advised by Prof. Trevor Darrell, and a member of Berkeley AI Research (BAIR). I am spending this summer as a research intern at Meta FAIR, and will continue at Meta as a Visiting Researcher. I also work closely with Prof. Sewon Min.

I received my Bachelor's Degree from Peking University, where I was advised by Prof. Shanghang Zhang. I have also worked closely with Prof. Graham Neubig, Prof. Jim Glass, and Prof. Guangyu Robert Yang.

I build generalizable unified models. If you are interested, please feel free to reach out!
