Research Summary
I want to understand the origin of structure and matter in our cosmos. Some questions that interest me include: How did the universe first got populated with particles during the hot big bang (reheating after inflation)? What is the nature of dark matter? My expertise lies in exploring the nonlinear dynamics of cosmological fields -- both in the context of the early universe and the contemporary universe. On the mathematical side, I am fascinated by solitons, their interactions and their relevance to cosmology. I have also delved into problems related to understanding aspects of Hubble tension, dark energy, gravitational waves and CMB spectral distortions.
