Solar wind · Radio occultation · Planetary plasma

Student visitor, Space Physics Laboratory, Vikram Sarabhai Space Centre, Thiruvananthapuram.
I am a space physicist working at the intersection of radio science, planetary science, space weather, and data-driven research. My research uses spacecraft radio signals to study the solar corona, solar wind, interplanetary plasma, and planetary ionospheres, with observations from the Indian Mars Orbiter Mission, Chandrayaan-2, Chandrayaan-3, Akatsuki, and Venus Express.
I submitted my PhD thesis, Exploring Space Weather and Its Effect on Planetary Atmospheres Using Radio Occultation, in May 2026 under the supervision of Prof. Abhirup Datta, supported by the Prime Minister’s Research Fellowship (PMRF), awarded in October 2023. Before that I worked on AI/ML and orbital mechanics at ERETS Space London and on space-debris data at Armstrong Space Australia, which led me to scientific software. Outside research, I enjoy astronomy outreach, photography, and travel.
