The website of D.U.Th.'s Information Retrieval Unit is launched! Check it out for news and more updated info for projects, publications, events, students, courses, etc.
Graduated from the department of Computer Engineering & Informatics, University of Patras, Greece, on September 1996. Ph.D in Informatics (Information Retrieval & Information Systems group) from the Computing Science Department, University of Nijmegen, the Netherlands, on June 21, 2001. Postdoctoral Fellow at the Department of Information and Computing Sciences, Center for Geometry, Imaging and Virtual Environments, Utrecht University, the Netherlands, 2003-2005. Postdoctoral Fellow at the Department of Media Studies, Archives and Information Studies group, University of Amsterdam, the Netherlands, 2006-2009. Faculty member at the department of Electrical Engineering & Computer Engineering of Democritus University of Thrace, Greece, from November 2009 (elected on June 2007).
As of September 2011, I have 16+ years of experience in Information Retrieval, including teaching related courses, and circa 50 publications in the field. I have given numerous talks during conferences, at universities, and in the industry. For the impact of my publications (e.g. citation counts, etc), search me on Google Scholar, Microsoft Academic Search, and Scopus.

Other Activities
An active
member of the ImageCLEF
community (2010, 2011), as well as the
TREC
community (2000, 2001, 2007, 2008, 2010), participating
to controlled IR experiments and contributing to the shaping of the tasks.
Trivia
My Erdös number is 3 via the link:
This means that publishing with me will get you a decent Erdös number of 4 ;-)
The median Erdös number is 5; the mean is 4.65, and the standard deviation is 1.21.
