About me

I am a 2nd-year PhD student in the Department of Computer Science and Technology at Tsinghua University. I am supervised by Prof. Juanzi Li. I also work closely with Prof. Zhiyuan Liu. At the summer of 2019, I visited Mila and did research with Prof. Jian Tang. You can find my CV here.

My research interests lie in deep learning methods on Natural Language Processing and Knowledge Graph. My research goal is to bridge machine learning models and symbolic human knowledge.
