科研领域：Solar Physics （Solar eruptive events: Pre-evolution to the post-eruption processes）

My primary research interest lies in the multi-wavelength diagnostics of the pre-

evolution phase brightenings associated with the impending events such as the

flux-rope triggering, filament eruption and, solar flares. The scientific research

carried out by me in this direction resulted in the key findings mentioned as fol-

lows. Investigation of the flare plasma parameters in the various phases of the

eruptive phenomena enabled to establish the role of non-thermal electrons as well

as other heating mechanisms (conduction) to be responsible for the precursor X-ray

enhancements. Thermal characteristics of the flare plasma, derived by combining

X-ray spectra of unprecedented energy and temporal resolution from the Solar X-

ray Spectrometer (SOXS, Indian) and the SphinX (Polish) instruments revealed

the evolution of multi-temperature plasma from the rise to the gradual phase of

the flare. My acquaintance on the numerical simulations include the hydrodynamic

simulation employing Palermo-Harvard (PH) 1D code to deduce various plasma

parameters during the the evolution of flare loop and synthesis of H and Fe line

profiles using the RH 1D radiative transfer code (developer: Prof. H. Uitenbroek).

Further, during my PhD, I installed and prepared data-reduction pipeline of a

10-cm aperture H telescope at Physical Research Laboratory, India.
