I am a researcher of National Research Council Canada, a research organiation that has just passed its 100th birthday, and proudly 10 Nobel Laureates have worked as full-time researchers in NRC during the time. My research interests include natural language processing, spoken document understanding, and machine learning. I received my Ph.D. from the Department of Computer Science of the University of Toronto in 2010 and my Masters of Engineering from the Department of Computer Science and Technology of Tsinghua University in 2000. Before, I have also worked with various industry labs, either as a full-time researcher (Intel's China Research Center), visiting scholar (Microsoft Research Asia), or as a research intern (IBM T.J. Watson Research Center; Google Inc).

Our paper on semantic compositionality was awarded the Adam Kilgarriff *SEM Best Paper Award for Lexical Semantics at the Joint Conference on Lexical and Computational Semantics (*SEM), Denver, Colorado. [paper]
From July 1, 2016 to June 30, 2019, I will serve a three-year term (part-time) for NSERC (Natural Sciences and Engineering Research Council of Canada) as an Evaluation Group (EG) Member to evaluate Discovery Grants applications in the area of Computer Science (link).
Employing our Tree-LSTM, Qian Chen's recent work on Natural Language Inference (paper link) has achieved the the state-of-the-art results on the Stanford Natural Language Inference benchmark (link). (Qian is a vistinting student I co-supervised. He will visit me and Diana Inkpen at University of Ottawa.)
Our paper exploring neural nets for semantic compositionality, "DAG-Structured Recurrent Neural Networks for Semantic Compositionality" has been published at NAACL-2016 (link).
On Feb. 22, 2016, I gave a talk at Ottawa Machine Learning Meetup on "Deep Learning for Text Mining: Case Studies on Social Media and Medical Text" (talk announcement).
Between July and November 2015, I gave a couple of talks at the University of Toronto, McGill University, UMass medical school, University of Ottawa, and Baidu Inc. about our recent efforts on neural networks for semantics.
