In this thesis, the possibility of interpreting the solar and atmospheric neutrino data within the context of theoretical models is being explored. In particular, the implications of the Minimal Supersymmetric Standard Model augmented by a single U(1) anomalous family symmetry for neutrino masses and mixing angles are investigated. Motivated by the above results, the effect of introducing a proper second singlet pair is studied resulting to additional mass entries in the previous model. Also, renormalization effects on neutrino masses and mixing angles in a supersymmetric string-inspired SU(4)xSU(2)LxSU(2)RxU(1)X model are discussed. Lastly, D-brane inspired models are studied with U(3)xU(2)xU(1)N gauge symmetry in the context of split supersymmetry.
