“You are the origin without beginning,
middle or end. You have numberless arms,
and the sun and moon are among Your great
unlimited eyes. By Your own radiance
You are heating this entire universe”

-Bhagavad Gita, Chapter 11, Verse 19

My current research interests lie at the interface of Astrophysics and Cosmology, in particular on the Cosmic Microwave Background (CMB), large scale structure formation in the Universe and reionization process. The study of CMB by COBE, WMAP, and Planck, have already set up the building blocks of Cosmology by measuring the age, content, curvature of the Universe and constrained many other cosmological parameters which are used to describe the several properties of the Universe. Now the question comes what new information CMB can provide us when the next generation low noise and high resolution telescopes start to operate in the next few years? And my research venture starts from that point.
