Hello! I'm Sourabh


I am a Research Associate based at McGill University. My primary research area is Cosmology. In particular, I study how the next generation of radio telescopes, such as CHIME, CHORD, MeerKAT and the upcoming SKA will be able to address the fundamental questions in Cosmology: age, geometry and expansion rate of the Universe, understanding dark matter and dark energy, physics of the primordial Universe, Epoch of Reionization and Cosmic Dawn --when the first stars and galaxies were born.
