My research is primarily concerned with the mathematical modelling of physics of

  • solar/space plasmas;
  • sun-solar wind;
  • solar-terrestrial systems.

  • The study of processes occurring in such systems is crucially important for understanding the Sun, predicting Space Weather and understanding the dynamics of space and laboratory plasmas. This includes mathematical modelling of solar magnetic flux tubes and processes that heat and maintain the coronal plasma at multi-million degree temperatures; studying fundamental plasma processes such as waves and instabilities in inhomogeneous media; determining the physical parameters of solar magnetic structures.
