Abstract: Motivated by cosmological applications in this thesis we describe several string theory based models of the early Universe. The major property of these models is that they lead to inflationary-like expansion for early times. The interaction properties of fundamental strings, leading to the velocity dependent potentials are used to describe this accelerating expansion rate. Other types of extended objects such as fivebranes dual to fundamental strings are shown to lead to the similar cosmological implications. Our findings are consistent with recent astronomical observations of an accelerated expansion of the Universe and predict an asymptotically constant late time expansion rate.
