Personal Information

Î’orn in Athens, Greece in 1980. In 2010, I received my Ph.D. from Computer Engineering and Informatics Department of University of Patras, Greece, in the field of Optical Grid Networks. I also hold a M.Sc. degree (2006) in "Integrated Hardware and Software Systems" and a Diploma (2003) from the same department. In 2015, I completed my post-doc on "Decomposing optimization techniqUes using Distributed computing technologiEs".

From 2018 I am elected as an Assistant Professor at the department of the Digital Systems of the University of Peloponnese, where I teach data networks, optical networks and cloud computing.

I am member of the High Speed Communication Networks Laboratory (HSCNL) of the School of Electrical and Computer Engineering at the National Technical University of Athens and of the ΓΑΒ LAB at the Department of Telecommunications and Informatics of the University of Peloponnese.
