Introduction to superstring cosmology

This is a summary of lectures in superstring cosmology given by the author at the CORFU 2009 School and Workshops ''Theory - Cosmology - Phenomenology'', Corfu Institute, Greece, Sept. 6.-13, 2009. These lectures are based on some recent developments and ideas, in the framework of superstring theory, concerning the evolution and structure of the universe in (i) the very early ''non-geometric'' cosmological era, (ii) the intermediate ''radiation-like'' era and (iii) the late time cosmological era characterized by the electroweak phase transition.
