Academic Background
I completed my BSc & MSc from University of Delhi in 2016. Later on, I joined Indian Institute of Astrophysics, Bangalore in Jan, 2017 to pursue my research interest in Astrophysics and by the beginning of 2020, I moved to ARIES, Nainital to complete my thesis work.

Research Interest and Description
My primary interest is Solar Astrophysics. Particularly, I work on century long archived data to understand the long term variation in the Sun. I am also involved in developing automatic algorithm to extract different solar feature from such a large volume of data and finding the physical parameters from them. Apart from that I am also interested in Solar Dynamo theory to understand the magnetic cycle of the Sun.
