  I discuss neutrino mixing ansatze, such as the generalized Tri-bimaximal and
bi-large mixing patterns, and their utility in describing the oscillation data.
Unitarity tests and probes of the absolute neutrino mass scale are briefly
discussed. A short overview of neutrino mass generation is given. I discuss an
orbifold approach to the flavor problem and the resulting implications, e.g.
the golden quark-lepton mass relation, neutrinoless double beta decay and
neutrino oscillation predictions.
