Abstract:


Due to the ubiquity of smart-phones and mobile devices, location services
have become very popular and are in very high demand. As a result,
computer servers that offer location services face grand challenges in
terms of functionality, performance, and scalability. In this talk, I will
give my personal perspective on the current research directions in the
area of spatiotemporal data management; the underlying technology for
supporting location services. I will highlight research challenges related
to the expressiveness, indexing, optimization, and processing techniques
for location-based queries and services.

Biography

Walid G. Aref is a professor of computer science at Purdue University,
West Lafayette, Indiana (USA). His research interests are in extending the
functionality of database systems in support of emerging applications,
e.g., spatial, spatiotemporal, 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, Qatar National
Research Foundation, Purdue CERIAS and Cyber Centers, Panasonic, and
Microsoft. 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 the ACM Transactions on Spatial Algorithms
and Systems (ACM TSAS), 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 an
executive committee member and the past chair of the ACM Special Interest
Group on Spatial Information (SIGSPATIAL).
