Constantinos (Costas) Valagiannopoulos was born in Athens, Greece, in 1982. He received the Dipl. Eng. (Hons.) degree in Electrical Engineering from the National Technical University of Athens, Greece, in 2004, and the Ph.D. degree on Electromagnetic Theory (Best PhD Award) in 2009 from the same Institute. Between 2010 and 2015, he was a Postdoctoral Researcher in the Department of Electronics and Nanoengineering, Aalto University, Finland (AaltoReference). During the academic year 2014–2015, he was with the Laboratory of Metamaterials and Plasmonics, Department of Electrical and Computer Engineering, University of Texas at Austin, USA (AustinReference). From 2015, he is with Nazarbayev University, Kazakhstan where now serves as an Associate Professor in Department of Physics, School of Science and Technology. During the last three years, he has been a visiting Assistant Professor at Harvard (HarvardReference) and Southampton University (SouthamptonReference). His research interests include artificial metamaterials, graphene, and their applications in photonic devices manipulating the light (metasurfaces, absorbers, cloaks, lenses). He has authored or coauthored more than 80 works in international refereed scientific journals and presented numerous reports in international scientific conferences. He is currently participating as PI or co-PI in the successful execution of national and international winning research grants with total annual budget more than 250K USD.

Dr. Valagiannopoulos received the inaugural 2015 JOPT Research Excellence Award for his work: “Perfect absorption in graphene multilayers” and is a Senior Member of IEEE and OSA. He also received the International Chorafas Prize for the Best Doctoral Thesis in 2008, and the Academy of Finland Postdoctoral Grant for 2012–2015. He is a Senior Member of IEEE and OSA.
