Walid G. Aref is a professor of computer science at Purdue. His research interests are in extending
the functionality of database systems in support of emerging applications, e.g., spatial,
spatio-temporal, multimedia, biological, and sensor databases. He is also interested in query
processing, indexing, data mining, and geographic information systems (GIS). Professor Aref's
research has been supported by the National Science Foundation, the National Institute of Health,
Purdue Research Foundation, CERIAS, Panasonic, and Microsoft Corp. 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 CERIAS and Discovery Park Cyber Center. He is
an associate editor of the ACM Transactions of Database Systems (ACM TODS) and has been an editor of
the VLDB Journal. He is a senior member of the IEEE, and a member of the ACM. Professor Aref is the
current chair of the ACM Special Interest Group on Spatial Information (SIGSPATIAL).
