RESEARCH AND SUPERVISION

My main scientific interest is the multi-wavelength study of Solar flares and associated phenomena as well as other solar eruptive events. I am also working with the computation of magnetic helicity, which is conserved quantity. We are using this conserve quantity to understand the relation between the solar eruptive phenomena and its association with magnetic cloud, which is important to understand the space weather prospective.
