I am a PhD student in the Information Retrieval group and Data System group of the David R. Cheriton School of Computer Science at the University of Waterloo since 2015. My supervisors are Prof.Mark D. Smucker and Prof.Gordon V. Cormack.

My research interests include Information Retrieval, NLP and Machine Learning. Currently, I am working on High Recall system and trying to improve the efficiency of text classification. I am also trying to investigate on how to optimize the web search from the user behavior. And of course, I am playing with deep neural network.

Before studying at University of Waterloo, I obtained my bachelor's and master's degree from Harbin Institute of Technology(China), and the other dual master's degree from University Bordeaux 1(France). I have lived, studied and worked in Canada, US, France, Italy and China for more than three months. Traveling around the world is always my interest.
