Tie-Yan Liu

Overview

Tie-Yan Liu is the research manager of the Internet Economics & Computational Advertising (IECA) group of Microsoft Research Asia. His research interests include learning to rank, large-scale graph ranking, game theory, computational advertising, and micro-economics. So far, he has authored two books, more than 70 journal and conference papers and over 30 granted US / international patents. He is the co-author of the best student paper for SIGIR (2008), and the most cited paper for the Journal of Visual Communication and Image Representation (2004~2006). He is a program committee co-chair of RIAO (2010), a demo/exhibit co-chair of KDD (2012), a track chair of WWW (2011), an area chair of SIGIR (2008~2011) and AIRS (2009-2011), a co-chair of several workshops at SIGIR, ICML, and NIPS, and a program committee member of many international conferences. He is an associate editor of ACM Transactions on Information System (TOIS), an editorial board member of Information Retrieval Journal and ISRN Artificial Intelligence. He is a keynote speaker at PCM (2010) and CCIR (2011), a plenary panelist of KDD (2011), and a tutorial speaker at several conferences including SIGIR (2008, 2010), WWW (2008, 2009, 2011), and KDD (2012). Prior to joining Microsoft, he obtained his Ph.D. in electronic engineering from Tsinghua University. He is a senior member of the IEEE, the ACM, and the CCF. He is now an adjunct professor (PhD supervisor) of the University of Science and Technology of China.
