Biography

My research focuses on understanding the chemical environments where planets form. I study protoplanetary disks around very low-mass stars and T Tauri stars using observations from JWST and ALMA. Alongside observations, I use thermochemical modeling to identify key molecular diagnostics that help interpret the chemical composition of disks and the physical processes shaping them. I also model ices in disk environments with emphasis on their spectral appearance. By combining modeling and observations, my work aims to uncover how the building blocks of planets vary across different stellar hosts, and how these variations may influence the formation and composition of planetary systems.

Education

  • 2025 – PhD in Astronomy, University of Groningen, the Netherlands
  • 2020 – Master of Science in aerospace engineering with a focus on spaceflight, Delft University of Technology, the Netherlands
  • 2018 – Bachelor of Engineering in mechanical engineering, Sri Jayachamarajendra College of Engineering, India

Research Interests

I am interested in Planet-forming disks, planet formation, exoplanets, brown dwarfs, and low-mass stars.
