Biography

I obtained BSc and MSc diplomas with honours in Applied Mathematics and Computer Science from Peter the Great St. Petersburg Polytechnic University in Russia. After a brief employment at the Ioffe Institute (St. Petersburg, Russia), where I modelled non-linear strain solitary waves in solids, I started doctoral studies at École des Mines in Paris, France. The main objective of my research was the development of a monolithic finite-element framework for simulating thin fluid flow through contact interfaces between solids with rough surfaces. This framework permitted me to refine the current understanding of the transmissivity of contact interfaces, which is relevant for the sealing engineering as well as for geophysical sciences. I defended PhD thesis in March 2019 and joined School of Engineering at the University of Glasgow to participate in the project of simulation of crack propagation in reactor core’s irradiated graphite bricks. 

Current research

I participate in the development of MoFEM, an open-source finite-element code providing hierarchical and heterogeneous approximation, variety of approximation spaces and HPC capabilities for solving complex engineering and physical problems. In particular, I am interested in the following applications:

  • Brittle crack propagation under contact loading in the arbitrary Lagrangian-Eulerian description of motion,
  • Simulation of fluid flow in contact interfaces between solids with rough surfaces using hierarchical, heterogeneous and anisotropic approximation
