Olena Okhay graduated in Microelectronics and Semiconductor Devices by the National Technical University of Ukraine “Kyiv Polytechnic Institute” in 1999, investigating the thin films of high temperature superconductive materials prepared by pulsed lased deposition and liftoff lithography. In 2009 she received PhD degree in Materials Science & Engineering from the University of Aveiro, Portugal, studying strontium titanate-based films for tunable device applications under a personal PhD grant by Portuguese Foundation for Science and Technology (FCT). The completion of the PhD was accompanied by a short career break due to two maternities. However, in 2012 and also in 2015 Dr. Okhay won a personal 3-years post-doctoral grants by FCT to works on “New Thin Films Solar Cells Based on Graphene Oxide Modified by Ni-Quantum Dots” and “Ni doped carbon-based materials for sensor application”, respectively, at the TEMA, University of Aveiro. In 2018, she received short-time post-doc position in CICECO, University of Aveiro within “Multifunctional all-oxide nanostructures for electronic applications” project, financed by FCT, Portugal and investigated ferroelectric / thermoelectric materials. In 2018 Dr. Okhay was promoted to post-doc position within Project on Corporate R&D Cooperation entitled “SGH - SMART GREEN HOMES, financed by the Fundo Europeu de Desenvolvimento Regional (FEDER) through the Programa Operacional Competitividade e Internacionalização (POCI) with the goal of study of piezoelectric materials for nanopiezogenerators. Science January 2019 Dr. O. Okhay works in TEMA, University of Aveiro as Independent researcher. Her current work concentrated on materials for energy harvesting and storage. In particular, she works with 1D-2D carbon-family materials, different composites, including metal oxides/hydroxide, polymers, etc. She obtained 1st prize in XXXIX Meeting of the Portuguese Society for Microscopy and Cell Biology (2004) and Young Scientist Award in European Materials Research Society (E-MRS) 2008 Spring Meeting. She participated in COST actions, FAME international networks, Graphene Flagship-events as well as in many summer/winter schools and workshops on different scientific thematic for the improving of her personal research potential. Her four short time projects were supported by European Cooperation in Science and Technology (COST) as short time scientific missions (STSM) in Institute of Physics, Academy of Science of Czech Republic (2007), to Institute of Advanced Technologies for Energy Nicola Giordano (CNR - ITAE) of Messina, Italy (2019), to Jagiellonian University in Krakow, Poland (2022), and to University of Tirana, Albania (2024). Another two short research projects were awarded as Research Mobility Grant from The European Consortium of Innovative Universities (ECIU) to Tampere University, Finland (2019) and to Kaunas University of Technology, Lithuania (2022). In addition, she has many international collaborations resulted in publications. In total, Dr. Okhay (h=14 based on SCOPUS) published 50 papers and 4 book chapters. 6 articles are published in the in the TOP-5 journals and 9 are published in the in the TOP-10 journals of their areas. She is Guest editor in two Special Issues and Reviewer in 30 International Journals. She participated in International conferences with posters (about 30) and oral presentations (12 invited/keynotes talks) as well as member of the organizing committee.
