The goal of modern cosmology is to understand the beginning, expansion and fate of the universe,
components that make up the matter in the universe and the formation and evolution of structures
including galaxies and clusters in the universe. As a probe for this purpose, cosmologists often use the
distribution of luminous galaxies in the Universe. I work towards understanding the spatial distribu-
tion of galaxies in the Universe as a function of the underlying matter distribution in the Universe by
comparing theoretical models with observations and by using existing and novel statistical methods.
For this work, we use analytic models of structure formation in the Universe and cosmological numer-
ical simulations. This work is expected to unravel the nature of the galaxy-matter connection in the
Universe and contribute to better understanding the physics galaxy formation. I also work in under-
standing the statistical properties of radio emitting galaxies using numerical simulations. This work is
collaborative in nature and collaborations are given below.
