Royal Society-SERB Newton International Post-doctoral Fellow


Awarded jointly by the Royal Society, London, UK and SERB, India and hosted by Prof Ian McHardy at the School of Physics and Astronomy, University of Southampton, UK, I worked as a postdoctoral fellow on 'X-ray reverberation and X-ray/UV/optical  reverberation mapping in Seyfert galaxies'

IUCAA postdoctoral fellow


WIth the postdoctoral fellowship awarded by the Inter-University Center for Astronomy and Astrophysics (IUCAA), India, I worked on the broadly black hole and neutron star accretion physics, X-ray spectro-temporal data analysis, in-orbit calibration of LAXPC/AstroSat, design of the observation plan, pipeline software testing and production of scientific results.
