About Me

I am a research scientist at Meta AI. My research focues on natural language understanding. For my recent research, I am passionate about building open-domain AI/NLP systems that are capable of searching, encoding and reasoning with information from the web.

Prior to Meta, I got my Ph.D. from University of California, Santa Barbara in March, 2021 and my bachelor degree from University of Science and Technology of China in 2016.
