In this talk we analyze the sources of lepton flavor violation in the Minimal Supersymmetric Standard Model (MSSM) in the processes $l → l’ \gamma$ and $h → ll’$. Using the Flavor Expansion Theorem, a recently developed technique of a purely algebraic mass-insertion expansion of the amplitudes, we recover the direct analytic dependence of the results on the MSSM Lagrangian parameters. Both flavor-violating off-diagonal terms and flavor-conserving mass-insertions are considered. We also study the decoupling features of the amplitudes in the limit of heavy SUSY spectrum. The results are compared with calculations in the mass eigenstates basis (i.e. using the exact diagonalization of the mass matrices).
