Bio

I come from Cyprus. I graduated from the Electrical and Computer Engineering department of the National Technical University of Athens (NTUA), Greece, in 2002. In December 2007 I received the PhD degree from the Electrical Engineering department at the University of Southern California (USC) in Los Angeles. I was a member of the Networked Systems Performance and Design Lab . From January 2008 to July 2009 I was a Postdoctoral Research Scholar at the Cooperative Association for Internet Data Analysis (CAIDA) , University of California-San Diego (UCSD). From September 2009 to December 2010 I was a Visiting Lecturer at the Department of Electrical and Computer Engineering at the University of Cyprus . Since January 2011 I am a Lecturer at the Department of Electrical Engineering and Information Technology at the Cyprus University of Technology.

Research Interests

Scaling behavior of the performance of computer networks and methods for scalable performance prediction, navigability of complex networks, network topology, P2P systems, queueing theory, graph theory.
