Magnetohydrodynamic (MHD) waves: Numerical simulations, observations and associated Seismology
The solar atmospheric heating problem is still one of the outstanding problems in solar physics. MHD waves are one of the potential mechanisms that can heat the solar corona. Our group develops state-of-the-art models and performs space and ground-based observations to understand the nature of MHD waves and their potential to heat the solar atmosphere.

Solar Eruptions: Solar Flares and Coronal Mass Ejections
Solar flares and coronal mass ejections are among the largest eruptions of our solar system. They carry energies equivalent to 1 billion nuclear explosions. When directed towards Earth, these storms can cause disturbances in the geomagnetic field. Our group is engaged in understanding these eruptions and predicting their arrival time on Earth to mitigate their harmful effects. We are carrying out observational studies and numerical simulations of CMEs and their associated turbulence (Vashishtha et al 2025; Sheoran et al 2026).

Solar Wind: Origin and Evolution in the Heliosphere
Solar wind is the continuous stream of charged particles emanating from the Sun towards the Earth. Our group is engaged in understanding how the solar wind originates from the sun and is accelerated to high velocities. We are also exploring how the magnetic field topology of the Sun shapes the solar wind outflows.
Recently, I have started working on the turbulence in different parts of ICMEs and their comparison with the turbulence in solar wind (Sheoran et al, 2026).
AI/ML applications in solar physics
The Sun is our nearest star and the only one that can be resolved to spatial scales of a few hundred kilometres. Following the advent of space-age technology, multiwavelength observations of the Sun have been conducted. This has provided us with a wealth of data across various wavelengths. Our group is currently developing AI and machine learning models to automatically detect solar eruptions and other features.
