Bio

Originally from Beijing, China, I am currently a Ph.D. student in the NLP group at MIT CSAIL. I received my M.S. in computer science, B.S. in computer science, and B.A. in linguistics from the University of Washington.

I love computers, languages, and teaching computers to understand languages. For that, I have previously done research at the Allen Institute for Artificial Intelligence (AI2) (as a PYI), and at the University of Washington with Prof. Noah Smith and Prof. Fei Xia. I have also worked on many interesting NLP and machine learning problems in the industry when I interned at Google, Facebook Meta, and other places.

I co-organize NLP with Friends, a seminar series where we chat about NLP research. Come join us!

Two friends and I have also built a platform, cs-sop.org, where past applicants to CS PhD programs have generously shared their statements of purpose and other advice. We hope this could be a useful resource for future applicants.
