Amr_El_Abbadi_002Abstract. Data is everywhere, and is being used in all sorts of ways to derive valuable information.  Data is being generated, stored, managed and analyzed all around us at unprecedented rates. In fact, big data applications have become indispensable in as diverse fields as environmental engineering, commerce, astrophysics, neuroscience, social science and geographic applications. Large scale, globally dispersed data centers, also known as The Cloud, are the common eco-system for storing such big data sets.  Managing and manipulating big volume data sets in such settings raise significant data management concerns that have resulted in sacrifices in functionality or efficiency. In this talk, we will explore various approaches to mitigate the shortcomings incurred to ensure consistent data management both within a single data center as well as across multiple data centers.  Consistently managing data across geographically dispersed multiple data centers is crucial to ensure fault-tolerance in the face of catastrophic disasters. Velocity is another major concern when managing large on-line data. Given that “near things are more related than distant things”, we have been interested in the real-time detection of spatial significance in trending topics, eg, in Twitter.  We will discuss GeoScope, a recently proposed data streams solution that detects correlations between topics and locations.

Amr El Abbadi is a Professor of Computer Science at the University of California, Santa Barbara. He received his B. Eng. from Alexandria University, Egypt, and his Ph.D. from Cornell University. Prof. El Abbadi is an ACM Fellow, AAAS Fellow, and IEEE Fellow.  He was Chair of the Computer Science Department at UCSB from 2007 to 2011.  He has served as a journal editor for several database journals, including, currently, The VLDB Journal, IEEE Transactions on Computers and The Computer Journal. He has been Program Chair for multiple database and distributed systems conferences, most recently SIGSPATIAL GIS 2010, ACM Symposium on Cloud Computing (SoCC) 2011, COMAD (India) 2012 and the first ACM Conference on Social Networks (COSN) 2013. He currently serves on the executive committee of the IEEE Technical Committee on Data Engineering (TCDE) and was a board member of the VLDB Endowment from 2002 to 2008. In 2007, Prof. El Abbadi received the UCSB Senate Outstanding Mentorship Award. In 2013, his student, Sudipto Das received the SIGMOD Jim Gray Doctoral Best Dissertation Award. Most recently Prof. El Abbadi was the co-recipient of the Test of Time Award at EDBT/ICDT 2015. He has published over 300 articles in databases and distributed systems and has supervised over 30 PhD students.

The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.
