Current Research Interests

How was the Universe born? What will the Universe experience? I am studying the physics of dark energy, dark matter, and inflation in order to give an answer for these questions. In particular, I’m carefully researching evolutions of the matter density perturbation and the behaviors of the spherically symmetric solution in each model of dark energy and modified gravity. Dynamical system approach is being also used to investigate the general properties of the models.
