I am a postdoctoral research fellow at Harvard University (Harvard Medical School & BWH), working on medical natural language processing. I got my Ph.D. degree (deep learning for NLP) from Singapore University of Technology and Design (SUTD) with professor Yue Zhang. I was a visiting graduate student at University of Oxford.

My research interests are mainly focused on natural language processing (NLP) with machine learning approaches (especially deep learning models), as well as artificial intelligence (AI) in medicine and healthcare. I won the best paper at COLING 2018, best demo paper nomination at ACL 2018, and ISTD Best Dissertation Award. I served as the program committee of top-tier conferences: ACL/AAAI/IJCAI/EMNLP/NAACL/AMIA, I was selected as ACL 2018 outstanding reviewer, COLING 2018 outstanding reviewer, and NAACL 2019 Kudos reviewer. I am the developer of several popular NLP tools: NCRF++ and YEDDA, which attracted more than 2000 stars at GitHub. Here is my detailed CV.

I love badminton and swimming (Silver medal in Men's 100 metres freestyle at Chongqing University). I am in twitter.
