Biographical Information

Damianos Chatziantoniou received his B.Sc. in Applied Mathematics from the University of Athens (June 1991, summa cum laude) and continued his studies in Computer Science at Courant Institute of Mathematical Sciences of New York University (M.Sc., Dec. 1992) and Columbia University (M.Phil., Feb. 1996, Ph.D., June 1997). His academic research interests include big data, business intelligence (data warehousing, OLAP), large-scale analytics (MapReduce and beyond), query processing, data streams and real-time analysis. He has published more than 30 articles at top conferences and journals, such as VLDB, ICDE, EDBT, KDD, SIGMOD, Journal of Information Systems, Journal of Data and Knowledge Engineering and elsewhere. His research work has influenced Microsoft’s SQL Server (query processor), Oracle’s 8i and 9i Systems (Analytic Functions for OLAP, a benchmark for any BI system), and ANSI SQL Standard (OLAP Amendment). There are more than 11 U.S. patents using Damianos’ research work as primary reference (among these, 4 from Microsoft, 2 from IBM and 2 from Oracle) and more than 150 citations to his work, including 9 data management textbooks. He is currently an Assistant Professor at Athens University of Economics and Business (AUEB), Department of Management Science and Technology. Prior to AUEB, he has served as a tenure-track Assistant Professor at Stevens Institute of Technology (September 1997-December 1999.)



Besides academia, Damianos has been involved in several technology startups. Panakea Software Inc. (founder, 1998), based in New York City, developed and marketed database querying/reporting technology to make certain analytic tasks (OLAP) easier to express and faster to evaluate. Clients included Dun & Bradstreet, Columbia-Presbyterian Medical Center and Philips North America. VoiceWeb SA (founder, 2001), based in Athens, focused on speech and telecom applications. VoiceWeb is currently the leading company in the Balkans in speech-related applications. In 2011, Bank of Piraeus acquired a stake at Voiceweb. Clients include Vodafone, Wind, Alpha Bank, Village Cinemas, Athens Festival, etc. Damianos has served in 2007-2008 as a senior research consultant in Aster Data Systems, a high-profile database technology startup based on Silicon Valley, dealing with distributed data warehouses. Aster Data was acquired in March of 2011 by Teradata.
