News: I’m now working as a Senior Researcher with the database group at the Department of Computer Science, Oxford University, UK.

From September 2015 to March 2016, I was a Research Postdoctoral Assistant with the same group, at Oxford.

I did my PhD at the Department of Computer Science, Viterbi School of Engineering, University of Southern California. I was a member of the Information Integration Group, Intelligent Systems Division-Information Sciences Institute (ISI) at Marina Del Rey, CA. In the past, I have worked with the Information Systems Laboratory, Institute of Computer Science, Foundation for Research and Technology-Hellas (a.k.a. ICS-FORTH), Heraklion/Crete, Greece.
