Academic interests

My primary research focuses on the multi-wavelength investigation of solar jets and flares using space-based observatories, including the Solar Dynamics Observatory (SDO), Interface Region Imaging Spectrograph (IRIS), and Solar Terrestrial Relations Observatory (STEREO), as well as, more recently, the ground-based Swedish 1-m Solar Telescope (SST). Our work has utilized high-resolution observations to examine the role of magnetic flux emergence and arch filament systems in the initiation and evolution of solar jets. In collaboration with international research teams, I have conducted detailed imaging and spectroscopic analyses of solar jets and flares using IRIS and SST observations. More recently, together with my PhD student, I have expanded this research to investigate the fine-scale structure and dynamics of solar flare ribbons. My current research aims to unravel the origin and evolution of solar eruptions through high-resolution SST observations combined with comparisons to advanced numerical simulations and modeling efforts.

Background

I obtained my B.Sc. in 2012 and M.Sc. in Physics in 2014 from Kumaun University, Nainital, India. In August 2015, I joined the Department of Physics at DSB Campus, Kumaun University, as a Ph.D. candidate under the supervision of Prof. Ramesh Chandra. During my doctoral research, I worked on the topic "Study of Solar Jets and Related Flares", utilizing observations from a variety of space-borne and ground-based instruments to investigate the physical processes underlying solar jet activity and associated flare phenomena.
