He is the creator and leader of an EMC network (three academic and two industry laboratories). With his colleagues, he designed several innovative products like the Electric Impedance Tomography (EIT), the Microwave Landing System (MLS), the ORAMA simulator and the SMS-K monitoring system. He has supervised 31 Ph.D. dissertations and more than 100 postgraduate diploma theses. He is the author of three books in Greek, 9 book chapters, and more than 410 articles. He also is the author of the book The Orthogonal Methods of Array Synthesis-Theory and the ORAMA Computer Tool (Wiley, 2006). He has been on the editorial board of three scientific journals. He is a member of EuRAAP as a delegate of Cyprus, Greece, Israel and Turkey. Professor Sahalos is also a Life Fellow of IEEE.

Christos Kalialakis (Wattrelos, France, 1971) was awarded the Ph.D. Degree in Electronic and Electrical Engineering from the University of Birmingham, UK in 1999.   He received the B.Sc. in Physics and the Master in Telecommunications in 1993 and 1995 both from the Aristotle University of Thessaloniki (A.U.Th), Greece. He joined CTTC, Spain in 2015 as a Senior Researcher.
