    Personal profile


    I have joined Aston Institute of Photonic Technologies, Aston University as Marie S.-Curie MULTIPLY Research Fellow in October 2018. Prior this I worked as a Research Fellow in Department of Theoretical Physics at B. Verkin Institute for Low Temperature Physics and Engineering (Kharkiv, Ukraine). My higher education was obtained at V.N. Karazin Kharkiv National University, (BSc and MSc in Physics) and B. Verkin Institute for Low Temperature Physics and Engineering (PhD in Physics).

    Research Interests

    • Machine learning methods for optical communications;
    • Nonlinear Fourier transform (NFT) based optical communication systems;
    • Density functional theory (DFT) modelling of the structural and electronic properties.
