Short Bio

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; elected Lecturer on June 2007, hired on November 2009, promoted to Assistant Professor on June 2013.

As of September 2013, I have 18+ years of experience in Information Retrieval, including teaching related courses, and more than 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:

Other Activities

An active member of the ImageCLEF community (2010, 2011), as well as the TREC community (2000, 2001, 2007, 2008, 2010, 2013), participating to controlled IR experiments and contributing to the shaping of the tasks.

Trivia

My Erdös number is 3 via the link:

Avi Arampatzis (2004) -> Mar J. van Kreveld (1998) -> Boris Aronov (1994) -> Paul Erdös


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.
