Research

I am primarily interested in the physics of space plasmas. The study of processes occurring in such systems is important for understanding the fundamental properties of plasma, the unexplained heating of the solar/stellar atmospheres, acceleration of the solar wind. The main areas of my research are

• Magnetohydrodynamic (MHD) instabilities in compressible flows, nonlinear evolution of the instabilities;
• The dynamics of the solar atmosphere, numerical modelling of solar transients in coronal loops, synthesis of observables;
• Excitation and damping mechanisms of MHD waves in solar magnetic structures
