My main research interest is in cosmology, in particular in cosmic inflation and formation of the large scale structure of our Universe, the origin of the matter-antimatter asymmetry and dark energy of the Universe. Cosmic inflation is an epoch of a rapid and accelerated expansion of the very early Universe. By its rapid expansion, inflation can amplify quantum fluctuations of matter fields to produce a nearly scale invariant spectrum of cosmological pertubations, which get imprinted as temperature fluctuations on the cosmic microwave background radiation (CMBR) and in addition, they are believed to seed the large scale structre of our Universe. The question that interests me most is, what drives the primordial inflation, and to what extend can be determine the properties of cosmological perturbations from fundamental principles and physics. I find it equally fascinating to ponder on the origins of the matter-antimatter asymmetry, dark matter and the dark energy of the Universe. But more on these fascinating questions on my future website.
