My overall area of interest is early universe cosmology, in particular aspects of non-linear cosmological perturbations related to observational cosmology.

Non-Gaussianity (deviations from an exact Gaussian distribution of the primordial density perturbation), gravitational waves (tensor perturbation) and primordial Black holes are three aspects of cosmological perturbation, which bridge between theoretical cosmology and observation.

Their possible detection would help us to identify physical processes at work in the early Universe models. Establishing the early universe model, will able us to give greater clarity to the late universe problems like dark energy.

I am also intereste on models of early universe inflation such as Stocastic Inflation. In this model we try to have a beter understading of quantum mechanics effect, in early unioverse cosmology.
