Biographies of Officers


Mohamed Mokbel, University of Minnesota, USA

Mohamed Mokbel is an associate professor in the Department of Computer Science and Engineering, University of Minnesota. His current main research interests focus on providing database and platform support for spatial data, moving objects, and location-based services. His research work has been recognized by three best paper awards at IEEE MASS 2008, MDM 2009, and SSTD 2011, and by the NSF CAREER award 2010. Mohamed was the general co-chair of SSTD 2011 and program co-chair for MDM 2011, DMSN 2011, and LBSN 2011. Mohamed was also the proceeding chair of ACM SIGMOD 2010, and the program co-chair for ACM SIGSPATIAL GIS 2008, 2009, and 2010. He serves in the editorial board of IEEE Data Engineering Bulletin, Distributed and Parallel Databases Journal, and Journal of Spatial Information Science. Mohamed is an ACM and IEEE member and a founding member of ACM SIGSPATIAL. For more information, please visit: www.cs.umn.edu/~mokbel.
