• WebDB 2008 - The selective workshop on the Web and Databases is under way!

I am an Assistant Professor at the Computer Science & Engineering Department of University at Buffalo, SUNY. I completed my Ph.D. at the Computer Science & Engineering Department of University of California, San Diego in December 2005 under the supervision of Professor Yannis Papakonstantinou. In 2000, I received an MS degree in Computer Science, from University of California, San Diego, and in 1998, a Diploma in Computer Engineering from Technical University of Crete, in Greece. I also spent two years (2000-2001) at Enosys Software Inc.

• Data Integration (CSE 636) Spring 06, Fall 06, Fall 08
• Database Systems (CSE 562) Fall 07, Spring 09

• Databases and Web Technologies
• User-oriented and Agent-oriented Interfaces to Databases
• Semistructured and XML Data
• Publishing and Integration Scenarios
• Rewriting Queries using Limited Interfaces
• Schema Integration

My primary research area is in the intersection of databases and web technologies. I am particularly interested in enabling publishing and large-scale integration scenarios through the use of web-based interfaces to databases. I am currently working on the following projects contributing towards this direction:

• CLIDE
  Interactively formulating feasible queries on query rewriting-based systems.
• QSSL
  Query Set Specification Language: Development of database-oriented web services.
• QURSED
  Query forms and reports for semistructured data.

I am currently looking for PhD students to work with me on the above projects or related research topics. If you are interested, please send me an email.
