About me
Hello! I am Zijian Chen (“Steven”), a junior undergraduate student at the University of Waterloo, Canada. I am lucky to be advised by Prof. Jimmy Lin and Prof. Victor Zhong in their labs; I have also worked with Prof. Raquel Urtasun and Prof. John P. Hirdes during internships. My research interests are Information Retrieval (IR), and Natural Language Processing (NLP).
