 Short CV
 
Efstathios Stamatatos received the diploma degree in electrical engineering (1994) and the doctoral degree in electrical and computer engineering (2000), both from the University of Patras, Greece. He was a research associate of the Wire Communications Lab. of the University of Patras from 1995 to 2003. He also joined the Polytechnic University of Madrid (1998) as a visiting researcher, the Austrian Research Institute for Artificial Intelligence as a post-doc researcher (2001-2002), and the TEI of Ionian Islands as an adjunct professor (2002-2004). Since 2004 he is a faculty member of the Dept. of Information and Communication Systems Engineering, University of the Aegean.
