  Several classes of neutrino mass models, which can naturally account for
hierarchical masses and the bi-large pattern of neutrino mixing, are
constructed from a bottom-up perspective based on the idea of decoupling of one
right-chiral neutrino from the seesaw mechanism. The interplay between the
predictions for the lepton-flavour violation in the MSSM with universal soft
masses and for leptogenesis is studied. In particular, classes of neutrino mass
models in which successful leptogenesis implies BR(mu->e gamma) potentially
observable in upcoming experiments are identified.
