Nikos Sagias

Nikos Sagias was born in Athens, Greece, in 1974. He received the B.S. degree from the Department of Physics (DoP) at the University of Athens (UoA), Greece, in 1998. The M.S. and Ph.D. degrees in telecommunications engineering were also received from the UoA in 2000 and 2005, respectively. Since 2001, he has been involved in various national and European research and development projects for the Institute of Space Applications and Remote Sensing of the National Observatory of Athens, Greece. During 2006 and 2008, he was a Research Associate at the Laboratory of Mobile Communications of the Institute of Informatics and Telecommunications at the National Centre for Scientific Research "Demokritos," Athens, Greece. Currently, he is an Assistant Professor at the Department of Telecommunications Science and Technology of the University of Peloponnese, Tripolis, Greece. Dr. Sagias research interests are in the area of wireless digital communications, and more specifically in MIMO and cooperative diversity systems, fading channels, and communication theory issues. In his record, he has over thirty papers in prestigious international journals and more than twenty in the proceedings of world recognized conferences. He has been included in the Editorial Boards of the AEU International Journal of Electronics and Communications and the Research Letters in Communications, while he acts as a Reviewer for several international journals (IEEE Transactions, IEEE Communications Letters, Electronics Letters, etc.) and IEEE conferences (ICC, GLOBECOM, VTC, WCNC). Additionally, he is a Member of the IEEE, IEEE Communications Society, and Vehicular Technology Society as well as the Hellenic Physicists Association.
