I have completed integrated M.Tech. degree in Electronics and Communication Engineering with specialization in Wireless Communication and Networks from Gautam Buddha University, Greater Noida in 2017. I was the recipient of the gold medal award (throughout topper in B.Tech.+ M.Tech.) in the university. Presently I am working on ``Potential of dual-frequency polarimetry Synthetic Aperture Radar (SAR) data processing to estimate soil moisture and its application in flood prediction" at Indian Institute of Science Education and Research Bhopal. This research work is a part of the prestigious NASA-ISRO SAR (NISAR) mission.
