I am a theoretical cosmologist. My research focuses on some fundamental questions for cosmology, such as, the nature of the big bang, the origin and future destiny of our universe, how the black holes and the galaxies formed. Particularly I work on bounce cosmology, inflation in string theory, dark energy, cyclic universe, cosmic string, and black hole physics.
