Abstract: Heterotic orbifolds are simple and elegant string constructions that can produce appealing gauge symmetries and chiral matter. We discuss particularly how so-called local GUTs can help us to connect heterotic string theory with the MSSM through orbifolds. We address the question of how realistic these orbifold models are, focusing on aspects such as R-parity, supersymmetry breaking, see-saw neutrino masses, and possible solutions to the supersymmetric mu-term problem and strong CP problem. We also address the problem of moduli stabilization in this context.
