     Jiaheng Lu is a professor in Computer Science at Renmin University of China. He received Ph.D. degree from National University of Singapore. He did two year Postdoc research in University of California, Irvine, U.S. (2006~2008). He was exceptionally promoted to a full professor on account of the outstanding research and teaching performance (2012). His research interests span many aspects of data management and data analytics. His current research focuses on developing a new search engine for academic search called Panda Search, querying big graph data and Mapreduce performance optimization. He has served in the organization and program committees for various conferences, including SIGMOD, VLDB, ICDE and CIKM.
