Tatiana Giannakopoulou received her Diploma in Radiophysics and Electronics including Quantum Radiophysics from Kiev State Shevchenko University in 1985. She got her Ph.D. from the same university in 1993 entitled “Polarization properties of the diffusely scattered coherent electromagnetic radiation”. She worked at Kiev University as a research associate from 1985 to 1996. From 2000, she is with the NCSR Demokritos. She was involved in the research projects concerning electromagnetic properties of ferromagnetic, ferroelectric and conductive polymer materials for design of microwave absorbers as well as structural, optical and electrochemical properties of semiconductors, graphene and 2D nanostructures for applications in the photocatalysis and supercapacitors. She has experience in the nanomaterial fabrication routes such as sol-gel, hydrothermal and electrochemical deposition techniques and in the characterization techniques that include UV-visible light spectroscopy, conventional and attenuated total reflectance FT-IR, RAMAN spectroscopy, atomic force microscopy (AFM), scanning electron microscopy (SEM), cyclic voltammetry and electrochemical impedance spectroscopy.
