Xuanming (Billy) Zhang Hello! My name is Xuanming (Billy) Zhang, a second-year PhD student in Computer Science at Columbia University. I am fortunate to be advised by Prof. Zhou Yu and Prof. Lydia Chilton. I'm happy to be part of the Columbia NLP Lab and the Computational Design Lab. My research interests center around Natural Language Processing, Dialogue Systems and Human-AI Interaction. My goal is to develop practical NLP-powered systems that can be broadly applied to assist human-AI collaboration. Throughout my research journey, I am fortunately guided by so many awesome researchers and I really appreciate their help: Prof. Kathleen McKeown at Columbia University, Prof. Vincent Ng at University of Texas at Dallas, Prof. Zhiyuan Liu in THUNLP at Tsinghua University, and Prof. Dan Roth at Oracle. |
