Academic and Research Interests


My interests revolve around theoretical and observational understanding of the origin, evolution, future, and fundamental building blocks of our Universe. Do we need physics beyond the standard models of cosmology and particle physics in order to solve some of the most mysterious puzzles about the Cosmos? If yes, what are the promising directions? How can we test the cosmological standard model and its alternatives?
