I am a PhD student at the School of Electrical and Computer Engineering of the National Technical University of Athens (NTUA) as a member of the Knowledge and Database Systems Laboratory. I received my Diploma in Electrical and Computer Engineering from the School of Electrical and Computer Engineering of NTUA in 2005.

Starting from June 2012, I join the database lab at the University of California at Riverside. (PI: Vagelis Hristidis)

My research interests include: Profile-based and Context-aware Data Management, Personalization and Recommender Systems, skyline, top-k and ranked query processing.

As part of my research I have worked on the following:

• PrefDB system (joint work with G. Koutrika) To be demonstrated at SIGMOD Conference 2012
  • Worked on designing and implementing the PrefDB prototype system. PrefDB acts as a personalization layer on top of a relational DBMS and facilitates engineering and execution of applications that require preference processing. The prototype system has been implemented as a plug-in component running on top of PostgreSQL.
  • PrefDBAdmin: A graphical tool that helps application designers in the process of building, testing and fine-tuning preferential queries on top of a relational DBMS.
• Skyline Query Processing
  • Probalistic Contextual Skylines (refer to [pdf])
  • Skyline Queries for Market Analysis Problems (under submission)

I have also worked as a Graduate Research Assistant at the Institute for the Management of Information Systems - R.C. Athena (IMIS) (December 2008-June 2010), (Project: TALOS).

I have also served as an external reviewer for:

• the International Conference on Very Large Data Bases (VLDB)
• the International Conference on Extending Database Technology (EDBT)
• the ACM Conference on Information and Knowledge Management (CIKM)
• the East-European Conference on Advances in Databases and Information Systems (ADBIS)
• the International Conference on e-Business (ICE-B)
• the Data and Knowledge Engineering Journal (DKE)

as the Web Chair for:

• the 5th International Workshop on Personalized Access, Profile Management, and Context Awareness in Databases (PersDB) (in conjunction with VLDB 2011)
• the 4th International Workshop on Personalized Access, Profile Management, and Context Awareness in Databases (PersDB) (in conjunction with VLDB 2010)

and as a Staff Member for:

• the ACM SIGMOD/PODS Conference 2011, held in Athens Greece on June 12-16, 2011

Further, I have visited:

• Infolab at Stanford University (February-March 2010), (host Prof. Hector Garcia-Molina).
• Hong Kong University of Science and Technology (HKUST) (May-June 2009), (host Prof. Dimitris Papadias).

I have worked as a Teaching Assistant at the School of Electrical and Computer Engineering of the National Technical University of Athens (NTUA) on:

• Database Systems (3.4.26.7), 2009 - 2010 and 2010 - 2011
• Analysis and Design of Information Systems (3.4.59.9), 2007 - 2008
