Brief Biography

Constantinos Valagiannopoulos was born in Athens, Greece, in 1982. Between 2015 and 2023, he was a Faculty Member of the Department of Physics at Nazarbayev University (NU), Kazakhstan, until he got unanimously elected Assistant Professor at the School of Electrical and Computer Engineering of National Technical University of Athens (NTUA), Greece.

He leads the Metamaterials Modeling and Design Group performing research on the forward and inverse design of photonic devices manipulating the light as well as on the translation of electromagnetic concepts into quantum systems. He has authored or coauthored more than 130 works published at international refereed scientific journals and presented numerous reports in scientific conferences. He has participated as Principal Investigator (PI) or co-PI in the successful execution of national and international research grants with total budget surpassing 4M USD.

Between 2010 and 2014, he was a Postdoctoral Researcher in the Group of Theoretical and Applied Electromagnetics of Complex Media at the Department of Electronics and Nanoengineering of Aalto University, Finland (advisor: Sergei Tretyakov). He has spent the academic year 2014-2015 with the Laboratory of Metamaterials and Plasmonics at the Department of Electrical and Computer Engineering, University of Texas at Austin, TX, USA (advisor: Andrea Alu). During 2016, he was a visiting scholar at the Theory of Materials Group of the Department of Physics at Harvard University, MA, USA (group of Efthimios Kaxiras) while in 2017 he has been a visiting Assistant Professor at the Quantum Polaritronics Group of the School of Physics and Astronomy, University of Southampton, UK (group of Pavlos Lagoudakis). Finally, he holds a Dipl. Eng. (Hons.) degree in Electrical Engineering from NTUA in 2004, and a Ph.D. degree on Electromagnetic Theory in 2009 from the same Institute.

Dr. Valagiannopoulos received the inaugural 2015 JOPT Research Excellence Award for his work: “Perfect absorption in graphene multilayers” and is a Senior Member of International Union of Radio Science (URSI) and OPTICA. He also received the International Dimitri Chorafas Foundation Prize for the Best Doctoral Thesis in 2008, the NTUA, the Thomaides PhD Thesis Award 2008, and the Academy of Finland Postdoctoral Grant for 2012-2015. He has won a Newton Al-Farabi Researcher Links Travel Grant for 2017 and has been the winner of the 2020 NU Teaching Award for Integrating Research and Teaching.
