Vassilis Katsouros received his M.Eng. degree in Electrical and Computer Engineering from the National Technical University of Athens (NTUA), Greece, in 1992.  In 1993 he obtained the M.Sc. with Distinction in Communications and Signal Processing from Imperial College of Science Technology and Medicine, University of London, UK.  From 1993 until 1997 he worked as research assistant in the interest group “Adaptive Control and Stochastic Systems” at the Interdisciplinary Research Centre for Process Systems Engineering (IRC-PSE) of Imperial College.  He was responsible for the research project “Statistical Analysis, Stochastic Modelling and Control of Flotation Processes”. During this period he gave tutorial lessons on electronics, mathematics and control methods in the Electrical Engineering Department, Imperial College. In 1997 received his Ph.D. degree from Imperial College. 

Since 1998 he has been working at the Institute for Language and Speech Processing (ILSP) and since 2000 was responsible of the Quality Assurance Office. In 2001 he was among the founding members of LibrisTech, the first spin-off company of ILSP, where he acted as managing director until September 2004.

In September 2004 he has elected Reseacher at ILSP and in December 2007 he was promoted to Senior Reseacher. Since July 2009 he has been elected member of the Scientific Board and has been appointed Deputy Director of ILSP for the period September 2009 - October 2010.

He has been supervised the quality assurance of more that 30 commercial software products and 6 web-portals developed by ILSP for third parties.  He has been involved in a numerous research projects at a national and European level. From 2000 to 2002 he was the scientific and administrative coordinator of the EU-funded FP5-IST project MYTHE. Since 2005 he has been working on projects that involve digitization and documentation of theatrical archives, archives of byzantine documents and digital archives of libraries. He has been involved in the supervision of 4 PhDs on text segmentation on image documents, handwriting recognition of mathematical symbols, speaker indexing and music transcription.

His research interests involve signal processing, probability and statistics, game theory, image processing and pattern recognition. He is a member of IEEE since 1992, ACM since 1999 and Technical Chamber of Greece since 1992.  Since 1999 he is a certified market maker/trader of the Derivatives Market at the Athens Exchange.
