Dr. Jinchuan Chen is an Associate Professor of the Key Laboratory of Data Engineering and Knowledge Engineering, Ministry of Education  (Renmin University of China). He received his Bachelor degree from Department of Computer Science and Technology of Beijing Normal University in 2001, and his Master degree from Institute of Software, Chinese Academy of Sciences in 2004. He then obtained his PhD from COMP (HKPolyU) in 2009. His research interests mainly focus on Uncertain Data Management and Unstructured Data Management.
