Cosmic Reionization Lyman-α Emitters Gravitational Lensing Dark Matter

About

Curious about the origins of structure in the universe and committed to sharing science beyond academia.

I am a research scholar at Tata Institute of Fundamental Research (TIFR), Mumbai. My work focuses on modelling the Lyman-alpha line profile of distant galaxies to probe the timeline of cosmic reionization and reveal how neutral hydrogen faded from the early universe.

Outside of core research, I actively communicate science through @50_shades_of_science, creating accessible explanations for complex astrophysical ideas. When I am not coding simulations or analysing galaxy surveys, you’ll find me playing the mouth organ or on a cricket field or just sleeping.
