About Me

I am a senior student at Dept. of Earth and Space Science, Peking University. I am currently a research assistant of Key Laboratory of Computational Linguistics in Peking University, advised by Prof. Xu Sun. I have spent some fun time interning at Software Analytics Group, Microsoft Research Asia (2017-2018), and DiDi AI Labs (2018). I also worked as the leader of team PKU Helper (2015-2018).

My research interests lie within deep learning for Natural Language Processing, particularly in dialogue systems and language understanding/representation. I am also involved in Machine Learning problems like optimization algorithms.
