My current research interests are mainly focused on the spectral analysis and analytical low-dimensional modelling of nonlinear, non-stationary, and multi-modal oscillatory processes in active regions of the solar atmosphere. In particular, my recent studies are related to the analysis of quasi-periodic processes in solar flares, Earth-size plasma faculae and pores oscillating at the surface of the Sun, oscillatory processes in coronal mass ejections (CMEs); theory of nonlinear oscillations in coronal current sheets and quisecent prominences.
In the past, I have studied theoretical aspects of nonlinear waves propagating in multi-fluid plasmas. Waves of different physical nature, such as Langmuir, dust- and ion-acoustic, Alfven, were considered. As a result, new types of highly nonlinear oscillations in plasma were discovered: super-nonlinear periodic and solitary (supersolitons) waves, both characterised by a non-trivial topology of their phase portraits, highly anharmonic profile shapes, extremely long periods and high amplitudes.
