Kosmas L. Tsakmakidis obtained his Diploma degree in Electrical & Computer Engineering from the Aristotle University of Thessaloniki, Greece (2002), his Master of Research (MRes) in Electronic Engineering from the University of Surrey, UK (2003), and his Doctorate degree (PhD) in Applied Physics and Engineering from the University of Surrey (2009).

From 2008-2013 he was a Royal Academy of Engineering/EPSRC research fellow, first at the University of Surrey (2008-2010), and then at Imperial College London (2011-2013). He subsequently worked as a senior postdoctoral research fellow at the University of California, Berkeley (2014-2015), a Eugen Lommel postdoctoral fellow at the Max Planck – University of Ottawa Center for Extreme and Quantum Photonics & the Department of Physics, University of Ottawa (Canada, 2015-2016), and as an EPFL Fellow at the Bioengineering Department, École Polytechnique Fédérale de Lausanne (EPFL), Lausanne (Switzerland, 2017-2018). Since March 2018 he is an assistant professor (tenured since Nov. 2021) in the Department of Physics of the National and Kapodistrian University of Athens, Greece.

He specializes in condensed matter photonics, nanophotonics, metamaterials, ‘slow’ and ‘fast’ light, computational physics, invisibility cloaking, and light-based chiral sensing schemes, where he has made a number of seminal contributions and introduced key concepts and results in the fields [e.g., K. L. Tsakmakidis, et al., Nature 450, 397 (2007); K. L. Tsakmakidis, et al., Phys. Rev. Lett. 112, 167401 (2014); K. L. Tsakmakidis, et al., Science 356, 1260 (2017); K. L. Tsakmakidis, et al., Science 358, eaan5196 (2017)]. For his work, he has received top-tier young-scientist awards by the Royal Academy of Engineering (UK, 2008), the Institute of Physics (best PhD Thesis prize, 2010), the UK Parliament, the Academy of Athens (Lycurgus Award, 2021), and the University of Surrey (Researcher of the Year, 2010), with his work often being covered by physics-dedicated and general-media outlets (e.g., APS Physics, Physics World, Physics Today, BBC, The Economist).
