Dr. Zisis Ioannidis is an Assistant Professor at the Department of Aerospace Science and Technology of the School of Sciences of the National and Kapodistrian University of Athens (NKUA). His area of expertise is "Applied Electromagnetics and High-Power Microwave Devices". He received the B.Sc. degree in Physics (2002), the M.Sc. degree in Electronics and Radioelectrology and the Ph.D. degree (2008) from NKUA. From 2009 to 2015 he worked as a postdoctoral researcher for the National and Kapodistrian University of Athens as well as for the Technological Educational Institute of Piraeus. In parallel he worked as a laboratory instructor for the Department of Electronics of the School of Pedagogical and Technological Education (ASPETE) and the Technological Educational Institute of Piraeus.  From 2016 to 2021 he joined the Institute for Pulsed Power and Microwave Technology (IHM) of the Karlsruhe Institute of Technology (Karlsruhe Institute of Technology), Germany. His was mainly responsible for the development and study of high-power, high-frequency gyrotrons, as well as for the design and development of prototype diagnostic devices for performing complex measurements in the microwave frequency range.

His research interests include electromagnetic theory, focusing on the interaction of electromagnetic waves with electron beams for the development of microwave oscillators with applications in experimental thermonuclear fusion devices, the propagation and scattering of electromagnetic waves in dielectric media with anisotropy and in homogeneity with applications in plasmas, and the design and development of active microwave pulse-compression devices with applications in directed electromagnetic energy systems. He has published 60 papers in peer-reviewed international journals and has contributed 137 papers & announcements to international scientific conferences.
