Ioannis Chremmos graduated in 2022 from the School of Electrical and Computer Engineering (SECE) with the highest honor among all graduates of the National Technical University of Athens (NTUA). In 2007 he completed his PhD in the same School in the field of “Electromagnetic analysis of the coupling between optical waveguides and resonators with integral equations” having been awarded successive scholarships by the Alexander S. Onassis Foundation and the Eugenides Foundation and offered scholarship by the Bodossaki Foundation. His doctoral research was awarded by the Chorafas Foundation and with one of the 12 worldwide graduate student fellowships of the IEEE Lasers and Electro-Optics Society.

He has worked in research projects at the NTUA Institute of Communication and Computer Systems (2008-2011), as a postdoctoral researcher at the Department of Applied Mathematics of the University of Crete (2011-213) and at the Max-Planck-Institut für die Physik des Lichts (Erlangen, 2013-2015) and as a Visiting Researcher at the Sun Yat-sen University (Guangzhou, 2017).

He has published 51 articles in scientific journals (first author in 40), 25 articles in conference proceedings, received 2280 citations with h-index 21 (Google Scholar), and served as the lead editor and author of the compiled volume “Photonic Microresonator Research and Applications” by Springer. His research on optical angular momentum multiplexing has been published twice in the top physics journal Physical Review Letters and granted an international patent.

He has taught lectures of Physics, Electromagnetism, Optical Fibers and Electrical Circuits at the Technological Education Institute of Piraeus, the Higher School of Pedagogical and Technological Education and the Hellenic Army Signal Corps School, while during the last 3 years he has been teaching Electromagnetic Fields as Adjunct Assistant Professor of the NTUA SECE. His research interests focus on electromagnetic and wave theory with applications in classical and quantum Optics and Photonics.

Since 2015 he has been working at HEDNO, initially at the Department of Islands and in the area of network protection and renewable power stations, while since 2023 he focuses on energy losses of the distribution network as Head of the Energy Efficiency Sector at the Network Department.
