As of July 2010, I am no longer at Buffalo.
Please follow my LinkedIn profile.

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.

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.
• BioNav
  Effective navigation on query results of biomedical databases.
• FACeTOR
  Cost-driven exploration of faceted query results.
• QURSED
  Query forms and reports for semistructured data.
• QSSL
  Query Set Specification Language: Development of database-oriented web services.
