Walid G. Aref
Professor of Computer Science
Joined department: 1999
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 streaming, and geographic information
systems (GIS). Walid's research has been supported by the National
Science Foundation, the National Institute of Health,
Purdue Research Foundation, Qatar National 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. Walid is a
member of Purdue's CERIAS. He is an associate editor of the ACM
Transactions of Database Systems (ACM TODS) and the ACM Transactions of
Spatial Algorithms and Systems (ACM TSAS), and has been an editor of the
VLDB Journal. Walid has won several best paper
awards including the 2016 VLDB ten-year best paper award. He is a
senior member of the IEEE, and a member of the ACM. Walid is an
executive committee member and the past chair of the ACM Special
Interest Group on Spatial Information (SIGSPATIAL).
