Recent measurements of the values of gauge coupling constants as well as
neutrino properties support the idea of a grand unified (GUT) description of
particle physics at a large scale of MGUT​∼1016 GeV. We discuss a
strategy to incorporate this picture in the framework of superstring theory. In
such a scheme successful predictions of GUTs can be realized while some of the
more problematic aspects of grand unification might be avoided. The most
promising models are expected in the framework of the heterotic E8​×E8​
string theory.Comment: Based on talks given at the conference on ``String Phenomenology
2004, Ann Arbor, and ``Pascos04-NathFest Symposium'', Boston, August 200
