He received the Diploma in Electrical and Computer Engineering from the National Technical University of Athens in 2002. In 2004 and 2007 he received respectively the MSc and PhD degrees in Electrical Engineering from the University of Southern California. During 2007-2009 he was a postdoctoral researcher at the Center for Applied Internet Data Analysis at the University of California, San Diego. His research interests are in network theory and network geometry. Particularly, his interests include: geometric approaches to the analysis and prediction of real networks; navigation/routing in complex networks; statistical inference and network mapping; geometry and correlations in real multiplex networks; network performance; and large-scale simulation.
