I am a Ph.D. student in Computer Science at UCSD advised by Jingbo Shang. Previously, I was an AI resident at Google Research. I received my B.A. in Computational Linguistics from Peking University.
I pursued research in Natural Language Processing (NLP) because of my multidisciplinary education in both humanities and computer science. My goal is to develop cutting-edge language technologies that are deeply attuned to human behaviors and values, which I refer to as human-centric AI. This involves: (1) language capacity, (2) reasoning ability, and (3) human values. I am honored to be selected as a DeepMind Scholar.
