Prof. Srianand is involved in various observational and theoretical projects: 1) probing the physical conditions in the high-z proto-galaxies traced by DLAs, 2) probing the time and space variation of fundamental constants using very high resolution spectra of QSOs, 3) tracing the redshift evolution of the CMB temperature using fine-structure lines and 4) semi-analytic modelling of formation and evolution of IGM, reionization and redshift evolution of global star formation rate density in the universe.

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.

Prof. Sahni works mainly in cosmology. His work on inflation includes a formulation of the cosmic no-hair theorem. He is also interested in the relic gravity wave background from inflation and its effects on the CMB. He also works on higher-dimensional braneworld cosmology, assessing its effects both on the early universe and at later times, as a candidate for dark energy. Prof. Sahni has developed a model-independent methodology for reconstructing properties of dark energy from observations. He is deeply interested in gravitational clustering and in the morphology of the supercluster-void network, having developed with collaborators a powerful diagnostic called the Shapefinder to determine the topological and geometric properties of the cosmic web.
