I am currently a postdoctoral researcher in computational linguistics, working on "Neural Pronoun Models in MT" project with Christian Hardmeier. I obtained my doctoral degree here in Uppsala and was supervised by Joakim Nivre and Rico Sennrich . Before joining Uppsala NLP group, I got my M.Eng, B.Eng from Beijing Language and Culture University and Shandong University in 2016 and 2013, respectively.

News ~

  • Our paper "Revisiting Negation in Neural Machine Translation" is accepted by TACL. It will appear soon~
  • I successfully defended my thesis, thanks the opponent: Philipp Koehn, and the committe numbers: Alexander Fraser, Arianna Bisazza, and Christian Hardmeier

I like various sports, recently I play badminton every week. I also like hiking and some challenging sports. I used to cycle a lot, and I spent 26 days to cycle from Chengdu to Lhasa along National Road 318 which is one of the most beautifual and most dangerous road in China.
