Dr. Tatiana Giannakopoulou received her Diploma in Radiophysics and Electronics including Quantum Radiophysics from Kyiv State University Taras Shevchenko in 1985. She earned her Ph.D. degree from the same university in 1993 performing thesis entitled “Polarization properties of the diffusely scattered coherent electromagnetic radiation”. She carried out her research on construction and optimization of automated Stokes polarimeters, non-invasive polarimetric methods of material investigation as a scientific researcher at the Polarimetry Laboratory of Kyiv University from 1985 until 1996.

Since 2000, she is with the NCSR Demokritos. In the beginning, she was involved in the research projects concerning electromagnetic properties of ferromagnetic, ferroelectric and conductive polymer materials for design of the microwave absorbers with the Sol-Gel Laboratory. Then, she joined the Laboratory of Nanofunctional and Nanocomposite Materials being engaged in the projects focussed on the development of nanostructured materials with targeted functionalities and properties (photocatalytic, hydrophilic/hydrophobic, antibacterial, electromagnetic shielding, energy storage etc.) for environment and energy applications. Such materials include inorganic and organic semiconductors (TiO₂, Ag₃PO₄, g-C₃N₄ and their heterostructures), carbon nanotubes, graphene and 2D graphene-like nanomaterials (g-C₃N₄ and MXene). At the present time, she is working at the Epitaxy and Surface Science Laboratory on the engineering and characterization of novel 2D phases for SiC and hBN, which are not existing in Nature in the bulk form, with the aim to be applied in nanoelectronics and ferroelectric memory devices.

Dr. Giannakopoulou has an experience in the description/calculation of thin semiconductor films via optical dispersion models, in the nanomaterial fabrication routes such as sol-gel, hydrothermal, electrochemical deposition, chemical vapour deposition (CVD) 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.  Dr. Giannakopoulou has 71 publications in peer-reviewed scholar journals with ~ 4055 citations, h-index 34 (Google Scholar 22-12-2025) and more that 60 presentations at national and international conferences.
