My main research interest lies in theoretical cosmology. I am interested in explaining the late time acceleration of the Universe. I am also studying how the structure in our Universe evolved from small fluctuations into a non-linear regime.
Within the context of general relativity, the observed accelerated expansion can be explained by invoking Einstein cosmological. However, a dynamical form of dark energy may exist which could possibly interact with dark matter. For this reason, I also work on interacting dark energy-dark matter models and in unified dark matter models in which a single dark component tries to explain both the acceleration and structure formation.
