I am currently a Ph.D candidate at School of Information Systems, Singapore Management University (SMU), under the supervision of Prof. Jing JiangI received my Bachelor and Master degrees from School of Computer Science and Engineering, NUST (Nanjing, China). During my Master Program, I was supervised by Prof. Shumei Wang and Prof. Rui Xia.

Now I focus on applying deep learning methods to some NLP tasks like Relation Extraction, Sentiment Analysis, etc. Also, I am interested in solving domain adaptation problems in NLP tasks.
