Abstract: In my talk I will review some of my work on fermion masses in Grand Unified Theories (GUTs). In the first part, I will focus on the question how realistic GUT predictions for fermion masses are. Interestingly, as I will discuss lattice data for light quark masses and neutrino oscillation data provide non-trivial constraints on GUTs. Then I will also focus on the little hierarchy problem and discuss naturalness in the general MSSM assuming that SUSY is broken at the GUT scale. It turns out that even after the Higgs discovery there are still regions with an acceptable amount of fine-tuning allowed.
