    Education

    PhD, Kumaun University (2021)

    About

    I have done my PhD from Kumaun University, Nainital, India in 2021 and received IAU best thesis prize for that. Lateran I joined University of Oslo for a postdoc position from 2022-2025 and NASA Goddard Space Flight Center & GMU from 2025-2026. Currently I am a researcher at University of Oslo.
