George C. Alexandropoulos

About

George C. Alexandropoulos received the Engineering Diploma (5 years) in Computer Engineering and Informatics, the M.A.Sc. degree (with distinction) in Signal Processing and Communications, and the Ph.D. degree (best Ph.D. thesis award) from the Computer Engineering and Informatics Department, School of Engineering, University of Patras (UoP), Rio-Patras, Greece in 2003, 2005, and 2010, respectively. He is currently an Associate Professor for Signal Processing for Wireless Communications at the Department of Informatics and Telecommunications, National and Kapodistrian University of Athens, Greece, mainly working in the general areas of algorithmic design, optimization, and performance analysis for wireless communication networks. He has held R&D positions at the Universities of Patras and of the Peloponnese, Technical University of Crete, National Center for Scientific Research-“Demokritos,” National Observatory of Athens, Athens Information Technology, as well as at the Mathematical and Algorithmic Sciences Lab, Paris Research Center, Huawei Technologies France. For his research and development activity under the latter industrial position, he received the IEEE Communications Society Best Young Professional in Industry Award 2018.
