About me

I received the MEng and the PhD degree from the School of Electrical and Computer Engineering of National Technical University of Athens in 2004 and 2009, respectively. From 2005 to 2007 Ι was a member of the team responsible for planning the Greek DVD-T network, and participated in the ITU RRC-06 as GRC delegate.
In 2011 I moved to Tripolis, Greece, to follow a career in academia, so for the past 12 years I have been holding a Laboratory and Teaching Staff position at the Department of Informatics and Telecommunications of the University of Peloponnese; I am also a member of the Wireless and Mobile Communications laboratory of the affiliated department for the same period of time.
In 2021, I started an MBA program at the National and Kapodistrian University of Athens in an effort to acquire better people and project management skills but also, to have a peak at the world of business through the familiar academic environment.
My research interests span the areas of wireless communication systems and RF network planning, simulation and analysis of PHY key technologies regarding 3G/4G/5G wireless systems (heterogeneous networks, advanced antenna techniques, massive MIMO, relaying strategies, full-duplex).
As I get older I find myself juggling different kind of problems, most of the times far from technical. I have a childish love for perfection, that, however, I willingly sacrifice in favor of efficiency; the phrase "it works!" is one of my favorites. Gradually, as a job-oriented person, I developed a deep appreciation of well-structured work environments that cultivate healthy relations among colleagues, while, at the same time, a perpetual challenge for me is engaging and motivating younger researchers and students into adhering to teamwork and to a collaborative style of working.

Technical problems can be easy, when you have solved all the non-technical ones.
