About me
Hello! I am Zijian Chen (“Steven”), a third year undergraduate student at the University of Waterloo, Canada. I am lucky to be a part of the Data Systems Group, supervised by Prof. Jimmy Lin; I have also worked with Prof. Raquel Urtasun and Prof. John P. Hirdes. My research interests are Information Retrieval (IR), and Natural Language Processing (NLP).
