AI Research Scientist at Meta

Biography

I am currently a AI Research Scientist at Meta. I received my Ph.D. in Computer Science from Washington University in St. Louis. Prior to that, I earned dual Bachelor’s degrees in Communication Engineering from the University of Electronic Science and Technology of China and the University of Glasgow, graduating with First-Class Honours.
