Biographies of Officers

Hanan Samet, University of Maryland, USA

Dr. Hanan Samet is a Professor of Computer Science at the University of Maryland where he leads a number of research projects on the use of hierarchical data structures for database applications involving multimedia data such as spatial and image databases. His research group has developed the SAND spatial browser, the VASCO system of JAVA applets for visualizing and animating spatial indexes (http://www.cs.umd.edu/~hjs/quadtree/index.html), and the MARCO system for map retrieval by content which enables pictorial queries on a symbolic image database system. He is the author of the recent book "Foundations of Multidimensional and Metric Data Structures" published by Morgan-Kaufmann, San Francisco, CA, 2006 (http://www.mkp.com/multidimensional), which received an Honorable Mention Award (one of two with one first place winner) in the 2006 best book in Computer and Information Science competition from the Professional and Scholarly Publishers (PSP) Group of the American Publishers Association (AAP). He is also the author of "Design and Analysis of Spatial Data Structures" and "Applications of Spatial Data Structures: Computer Graphics, Image Processing and GIS" published by Addison-Wesley, Reading, MA, 1990, which are the first two books on spatial data structures. He has a Ph.D from Stanford University. He is a Fellow of the ACM, IEEE, and the International Association of Patter  Recognition (IAPR). In 1989-1991 he served as the Capital region representative on the ACM Council. For more details, see http://www.cs.umd.edu/~hjs.

Walid G. Aref, Purdue University, USA

Dr. Walid G. Aref is a Professor of computer science at Purdue. His research interests are in developing database technologies for emerging applications, e.g., spatial, spatio-temporal, multimedia, bioinformatics, and sensor databases. He is also interested in indexing, data mining, and geographic information systems (GIS). In 2001, he received the CAREER Award from the National Science Foundation and in 2004, he received a Purdue University Faculty Scholar award. Professor Aref is a member of Purdue's Discovery Park Bindley Bioscience and Cyber Centers. He is on the editorial board of the VLDB Journal and is a senior member of the IEEE. He served as the Program Committee Co-Chair of the ACMGIS Symposium on Geographic Information Systems in 2001. For more details, see http://www.cs.purdue.edu/~aref

Markus Schneider, University of Florida, USA

Dr. Markus Schneider is an Assistant Professor at the Department of Computer and Information Science and Engineering at the University of Florida. He holds a doctoral degree in Computer Science from the University of Hagen, Germany. He is the co-author of the book Moving Objects Databases, published by Morgan-Kaufmann in 2005 as well as two other books in this field. His research interests include spatial databases, spatio-temporal and moving objects databases, GIS, applied computational geometry, and extensible databases. He is on the editorial board of GeoInformatica and a recipient of the 2004 National Science Foundation CAREER Award. For more details, see http://www.cise.ufl.edu/~mschneid.

Chang-Tien Lu, Virginia Tech, USA

Dr. Chang-Tien Lu is an Assistant Professor in the Department of Computer Science at Virginia Polytechnic Institute and State University. He received an M.S. degree from the Georgia Institute of Technology, and a Ph.D. degree from the University of Minnesota. He served as Program Co-Chair for the 2006 IEEE International Conference on Tools with Artificial Intelligence and the 2007 IEEE International Workshop on Spatial and Spatial-temporal Data Mining. Dr. Lu's research work focuses on emerging requirements for storing, analyzing, exchanging, visualizing, and disseminating spatial (and spatio-temporal) data in geospatial applications. His research group has developed several web-based spatial analysis and visualization systems for managing and mining various kinds of spatial information. Specific projects include discovering spatial anomalies, identifying recurrent or unexpected events, and predicting future trends. His research projects have been sponsored by the Department of Defense, the Virginia Department of Transportation, and the Virginia Transportation Research Council.
