Research interests

My research interests broadly include the study of,

• Inflationary cosmology

• Large scale structure - simulations and theoretical modelling

• Analysis of cosmological data, such as data from Cosmic microwave background, Large Scale Structure 

• Possible deviations from standard model of cosmology

• Reionization

• Dark energy

• Degeneracies in cosmology

I am mostly involved in numerical analysis of cosmological models. The codes I have developed are listed in the Developed Codes page of this website. Apart from comparing the models with the data, I also like to use different statistical techniques to reconstruct the theory from the data in model independent ways. 

Survey collaboration 

I am a member of CMB Bharat consortium collaboration and I led the Cosmological Parameters working group for our first proposal in response to the  Announcement of Opportunity (AO) by the Indian Space Research Organization (ISRO), submitted on April 16, 2018. The executive summary can be found here. The proposal is for a next generation space mission for near-ultimate measurements of the Cosmic Microwave Background (CMB) polarization and discovery of global CMB spectral distortions

Presently I am also a member of the Euclid Consortium Collaboration. Euclid is an ESA mission to map the geometry of the Universe by observing the shapes and spectra of the galaxies and clusters of galaxies. In this collaboration I work within the Theoretical Working Group.
