My primary research interests are to understand origin, evolution, propagation of solar radio bursts, and their associated coronal magnetic fields, weak energy events in the solar corona, solar wind turbulence using radio occultation technique. I am also interested in building radio instruments (such as imaging interferometers, radio spectrometers, radio polarimeters) to monitor the solar corona. Also, I took part in calibration, testing and various integration activities (both payload level and satellite level) of the Visible Emission Line Coronagraph (VELC) onboard Aditya-L1 mission.
