Prof. Souradeep is a cosmologist working primarily on CMB anisotropy and polarization. His work has dwelt on the cosmological ramifications of physics in the early universe. He has worked on diverse topics from quantum cosmology, generation of primordial perturbations and CMB anisotropy to observational issues and parameter estimation. Prof. Souradeep is currently developing novel analysis techniques for WMAP and the upcoming Planck Surveyor mission with the goal of hunting for signatures of new physics such as violation of statistical isotropy, cosmic topology and the relic cosmological gravity wave background.
