George Alexandropoulos joined the Department of Informatics and Telecommunications, School of Sciences, National and Kapodistrian University of Athens (NKUA) (also known shortly as University of Athens), Athens, Greece and is currently an Associate Professor for Wireless Communication Systems and Signal Processing at its Communications and Signal Processing division. He researches in the general area of algorithmic design, optimization, and performance analysis for wireless communication networks with emphasis on multi-antenna transceiver hardware architectures, full duplex radios, active and passive reconfigurable metasurfaces, integrated sensing and communications, millimeter wave and THz communications, and distributed machine learning. He is currently serving, or has served, as an Editor for various IEEE, Elsevier, and ITU journals (including IEEE Transactions on Communications, IEEE Transactions on Wireless Communications, IEEE Transactions on Green Communications and Networking, IEEE Communications Letters, and IEEE Wireless Communications Letters), as well as acting as a Reviewer, Member of the Technical Program Committee, and Chair for many top-level international journals and conferences on signal processing and wireless communications.Prof. Aryan Kaushik is Director of OUF Innovative (UK). Previously he has been Associate Professor at Manchester Met (UK), Assistant Professor at University of Sussex (UK), and Research Fellow at UCL (UK). He has also held visiting positions at leading institutions across UK, Luxembourg, Italy, China, etc. Recognized among the Stanford/Elsevier World’s Top 2% Scientists, he serves as an international assessor, PhD examiner, and funding evaluator. He chairs IEEE ComSoc TWG-ESIT and SIG-AITNTN, serves as one6G WG3 Vice-Chair, has edited five books, received seven IEEE Exemplary Editor Awards, and has delivered over 150 talks worldwide while chairing numerous flagship IEEE conferences.
