Profile
I am a researcher at the Yahoo! Research in Barcelona, Spain. I have studied in Greece and United Kingdom. My research interests include information retrieval models, web information retrieval, combination of evidence for information retrieval, hyperlink analysis, and architectures for large-scale distributed information retrieval. I am a member of ACM SIGIR and BCS IRSG.
