Title: 
The Dark Sector of the Universe on a D-brane
Abstract: 

I will discuss the possibility that the Dark Sector of the Universe is described by a moving D-brane in a string theory compactification. Dark energy is naturally identified with the scalar field parameterising the motion of the brane in the internal space, while Dark Matter is identified with the matter living on the world volume of the D-brane. In this scenario Dark Matter and Dark Energy are naturally coupled, with the coupling being determined by the theory in terms of the internal geometry. I will discuss the interesting cosmological solutions resulting from this scenario.
