About

---

I am a 4th-year Ph.D. student in Computer Science at UC Santa Barbara, working with William Wang. I mainly work on Information Extraction, Question Answering and Reasoning over both structured and unstructured text data.

Before coming to UCSB, I received my bachelor degree from University of Science and Technology of China (1210) in 2016.
