String gas cosmology is an approach towards studying the effects ofsuperstring theory on early universe cosmology which is based on new symmetriesand new degrees of freedom of string theory. Within this context, it appearspossible to stabilize the moduli which describe the size and shape of the extraspatial dimensions without the need of introducing many extra tools such aswarping and fluxes. In this lecture, the recent progress towards modulistabilization in string gas cosmology is reviewed, and outstanding problems forthe scenario are discussed.Comment: 15 pages, 1 figure to be published in the proceedings of YKIS05, Yukawa Institute, Kyoto University, June 27 - July 1, 2005 (one reference updates
