I am a 3rd year 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 Mark D. Smucker and Gordon V. Cormack. I am also working closely with Jimmy Lin, Maura Grossman and Charlie Clarke.
My research interests include Information Retrieval, NLP and Machine Learning. Currently, my research focus on building High Recall Retrieval system and trying to improve the efficiency and effectiveness of relevant document retrieval [4,5,6,11,12]. Another part of my research is to investigate how to evaluate different retrieval systems from user behavior. And of course, I am also working on deep neural network and trying to apply it on solving Question Answering and High Recall problems [3,8,9,10].
Before studying at University of Waterloo, I studied at Harbin Institute of Technology. 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.
