Personal profile

General

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.

Employment

  • 10/2018 – current, Marie S.-Curie MULTIPLY Research Fellow, Aston University;
  • 11/2006 – 7/2018 Research Fellow, B. Verkin Institute for Low Temperature Physics and Engineering, Ukraine;
  • 08/2016 -11/2016 Visiting Fellow, Pavol Jozef Šafárik University in Košice, Slovakia;
  • 11/2003 – 10/2006 PhD student, B. Verkin Institute for Low Temperature Physics and Engineering,Ukraine;
  • 9/2003 – 2/2005 Research engineer, B. Verkin Institute for Low Temperature Physics and Engineering of the National Academy of Sciences of Ukraine.

Funding Applications and Awards
