Angela Amphawan received her Ph.D. in Optical Communications from the University of Oxford, UK. She then won the prestigious Fulbright Award to work on optical devices and networks at the Research Laboratory of Electronics and the MIT Media Lab, Massachusetts Institute of Technology, USA. She currently leads the Photonics Laboratory at Sunway University. Before joining Sunway University, she was Deputy Vice Chancellor of the University Malaysia of Computer Science & Engineering, and previously, Director of the Optical Technology Research Laboratory at Universiti Utara Malaysia. Prior to that, she lectured at Multimedia University and served as a Computing Officer at the University of Oxford, UK. She is currently on the National 5G Task Force for the development of 5G infrastructure. She also serves on the IEEE Joint Sensor and Nanotechnology Councils. In addition, she is on the Editorial Board of the APL Photonics journal under the American Institute of Physics and several other international journals. Hien Quoc Ngo (IEEE Fellow) received the B.S. degree in Electrical Engineering from the Ho Chi Minh City University of Technology, Vietnam, in 2007, the M.S. degree in Electronics and Radio Engineering from Kyung Hee University, South Korea, in 2010, and the Ph.D. degree in Communication Systems from Linköping University (LiU), Sweden, in 2015. In 2014, he visited Nokia Bell Labs, Murray Hill, New Jersey, USA. Hien Quoc Ngo is currently a Reader (Associate Professor) at Queen's University Belfast, UK. His main research interests include cellular/cell-free massive MIMO systems, integrated sensing and communications, reconfigurable intelligent surfaces, and physical layer security. He has co-authored many research papers in wireless communications and co-authored the Cambridge University Press textbook Fundamentals of Massive MIMO (2016). Dr. Hien Quoc Ngo currently serves as an editor for several reputed journals. Miguel López-Benítez received his Ph.D. degree in Telecommunication Engineering (highest distinction, summa cum laude) from the Department of Signal Theory and Communications of the Technical University of Catalonia, Barcelona, Spain, in 2011. From 2011 to 2013, he was a Research Fellow in the Centre for Communication Systems Research (currently the Institute for Communication Systems) at the University of Surrey, Guildford, UK. In 2013, he joined the Department of Electrical Engineering and Electronics at the University of Liverpool, UK, where he is currently a Senior Lecturer (Associate Professor). His research interests are in wireless communication systems, with special emphasis on several theoretical and experimental aspects of cellular mobile communication technologies, dynamic/shared spectrum access, and the wireless Internet of Things, among others. He is or has been the principal investigator of research projects competitively funded in the UK by the Engineering and Physical Sciences Research Council (EPSRC), the Department for Business, Energy and Industrial Strategy (BEIS), the Royal Society, and the UK-India Education and Research Initiative (UKIERI). He has also been involved in several European-funded projects. He has co-authored four book chapters and over 160 papers in refereed journals and recognized conferences.
