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. Using observations from missions including the Indian Mars Orbiter Mission, Chandrayaan-2, Chandrayaan-3, Akatsuki, and Venus Express, I apply signal and time-series analysis to investigate solar-wind speed, coronal electron density, plasma turbulence, and space-weather effects on planetary environments.
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. My doctoral research was supported by the Prime Minister’s Research Fellowship (PMRF), awarded in October 2023.
Alongside academic research, I have worked on AI/ML and orbital-mechanics algorithms at ERETS Space London and on data pipelines and space-debris analysis at Armstrong Space Australia. These experiences have expanded my interests into space situational awareness, scientific software, automation, data visualisation, and making complex scientific datasets more accessible and useful.
Outside research, I enjoy science communication, astronomy outreach, photography, and travel.
