I am an observational cosmologist, interested to study different aspects of fundamental physics, astrophysics and cosmological phenomena using Cosmic Microwave Background (CMB), large scale structure and gravitational waves as observational probes. My work encompasses theoretical analysis, numerical calculations and developing statistical tools to understand the imprints of cosmological & astrophysical phenomena from the observed data.

I have explored a new observational probe to ultra light axions which is feasible from ground-based CMB experiments such as Simons Observatory , CMB-S4 , proposed a new cosmological probe using gravitational waves to study cosmic perturbations from LISA , showed a new avenue to improve the constraints on dark energy parameters using the cross-correlation between supernovae and galaxies from the upcoming large scale structure surveys such as DESI , EUCLID , LSST , WFIRST , etc. You can find the details about my work in the research section.
