I am currently pursuing PhD from IIT, Kharagpur, India. I am also working as Scientist in ISRO, India. My area of interests is in the GNSS applications for modelling of Ocean, atmosphere and ionosphere. I am also involved in the performance of GNSS receiver onboard ISRO LEO satellites and generation of IRNSS precise products. I also worked on the modelling of Polar Ice and Ocean using Indian Scatterometer and Altimeter data.
