Biography

Chen Xu is currently an associate professor at School of Data Science and Engineering, East China Normal University. Chen got his PhD degree in 2014 from Institute for Data Sciences and Engineering, East China Normal University, supervised by Prof. Aoying Zhou and also worked with A/Prof. Minqi Zhou. From Nov 2011 to Jan 2012, Chen severed at ECNU-MediaV Joint Lab of Computational Advertising as a research intern. From April to July in 2011, Chen studied as a visiting student at Data & Knowledge Engineering (DKE) Group, The University of Queensland, hosted by Prof. Xiaofang Zhou and Dr. Mohamed A. Sharaf. In 2009, Chen received the Bachelor Degree from Department of Computer Science & Technology, Hefei University of Technology. From 2014 to 2018, Chen conducted postdoctoral research with Prof. Dr. Volker Markl at Database Systems and Information Management (DIMA) Group, Technische Universität Berlin, as a senior research associate supported by Berlin Big Data Center (BBDC) project. His research interest is large-scale data management.
