About Me

I had graduated with Master's degree from Physics Faculty of St.-Petersburg State University (Russia) in condensed matter physics in 2008, followed by Doctor of Philosophy degree from University of Tartu (Estonia) in materials science in 2012. Then I have been conducting materials research in academic institutions of Germany, Italy, Russia. Since 2022 I have joined the Sustainable Polymer Chemistry group at the Faculty of Science and Technology, University of Twente as a Senior Postdoctoral Researcher.

While my professional interests are physics, materials science, I find inspiration in music, classical artsretro technology and Western philosophy.

Research

My doctoral thesis in materials science "Structural and tribological properties of zero- and one-dimensional nanocrystals" publicly defended in University of Tartu (Estonia) in 2012 had set an initial vector for my further research.

In 2016-2017 I had been a guest scientist at Forschungszentrum Juelich (Germany), where I had been collaborating with Dr. Bo Persson and Prof. Gert Heinrich (Leibniz Institute of Polymer Research Dresden, Germany) in the field of soft matter tribology.

In 2018-2019 I had been a guest scientist at University of Padova (Italy) in the lab of Prof. Lucia Nicola, where I had been collaborating in the field of computational contact mechanics.

In 2019-2022 I had been a Research Fellow in ITMO University (Russia) and in 2021-2022 became an Associate Professor in the same university.

Since 2022 I have joined the Sustainable Polymer Chemistry group at the Faculty of Science and Technology, University of Twente as a Senior Postdoctoral Researcher, where I have started collaboration with Prof. Sissi de Beer.

 

My academic fields of interest in materials science and physics:

  • Soft matter tribology, adhesion, viscoelastic and polymer materials, rough surface science.
  • Nanomechanics, in particular, tribology, manipulation, mechanical testing of nanoscale objects; numerical simulations of nanomechanical systems.
  • Theory of defects in solids in the framework of continuum mechanics and defects dynamics in nanostructured materials.
  • Kinetic quantum transport theory in solid state matter: conductors and semiconductors.
