Reseach Related information: 

My research focuses on understanding the dynamics and thermodynamics of the solar atmosphere and heliosphere using numerical magnetohydrodynamic (MHD) simulations and forward modelling to generate synthetic observations. I investigate the formation, evolution, and eruption of magnetic flux ropes, magnetic reconnection, and the associated solar eruptive phenomena. A major component of my research concerns the multi-thermal nature of the solar corona, including plasma heating and cooling, thermal instability, prominence formation, and coronal rain. I also employ synthetic imaging and spectroscopic diagnostics to connect numerical models with multi-wavelength observations from current and upcoming solar observatories. My broader research interests include the propagation and evolution of solar eruptions through the heliosphere and their implications for solar–terrestrial interactions.
