About

In 2008 I graduated from Moscow State University in the Physics Department (Chair of Mathematics), where I prepared my Master thesis devoted to "Dynamics of coherent structures in collisionless plasma." After two years, I defended the Ph.D. thesis "Stability of thin current sheets and charged particle acceleration" at the Space Research Institute (Moscow), Russian Academy of Science. The advisor of my Ph.D. thesis was Prof. Lev Zelenyi. In the period from 2011-2013 I was working in the LPC2E/CNRS laboratory in Orleans (France), in the scientific group headed by Dr. Vladimir Krasnoselskikh. In 2013 I came back to the Space Research Institute (Moscow), and since 2015 I have been working at UCLA.

Research Topics

  • Theory of resonant acceleration of charged particles: models of surfing acceleration and effects of random field fluctuations on resonant wave-particle interaction.
  • Charged particle dynamics in strongly curved magnetic fields: analytical theory of the adiabatic particle motion in the magnetic fields with complex configurations.
  • Spacecraft data analysis: observations of mesoscale structures (current sheets and dipoliarization fronts) by multispacecraft missions Interball, Cluster, Themis in the Earth magnetosphere and comparison of observations with theoretical models.
  • Resonant charged particle scattering and acceleration in the inner magnetosphere: wave-particle nonlinear interaction, quasi-linear theory.
  • Kinetic theory of plasma instabilities in current sheet: tearing instability in thin current sheets as a trigger of substorms in Earth magnetosphere, theory of drift instabilities and drift-tearing modes interaction. Comparison theoretical models of current sheet dynamics with spacecraft observations in Earth magnetosphere.
  • Particle interaction with turbulent electromagnetic fields (numerical modeling of particle acceleration and transport in the electromagnetic turbulence)
  • Dynamical chaos and destruction of adiabaticity in Hamiltonian systems: theory of separatrix crossings, adiabatic invariant destruction
