Moduli stabilization and supersymmetry breaking are among the outstanding problems in string phenomenology. Type IIB compactification with fluxes has shown to provide a concrete framework to analyze these two problems simultaneously in a controlled stringy manner. To explore quantitative issues of this scenario, however, it is essential to construct some explicit models where the Standard Model is embedded. In this talk, I will describe the first examples of such MSSM flux vacua and discuss issues involved in these constructions.
