  We investigate nuclear mu-e conversion in the framework of an effective
Lagrangian arising from the inverse seesaw model of neutrino masses. We
consider lepton flavour violation interactions that arise from short range
(non-photonic) as well as long range (photonic) contributions. Upper bounds for
the LFV parameters characterizing mu-e conversion are derived in the inverse
seesaw model Lagrangian using the available limits on the mu-e conversion
branching ratio, as well as the expected sensitivities of upcoming experiments.
We comment on the relative importance of these two types of contributions and
their relationship with the measured solar neutrino mixing angle theta_12 and
the dependence on theta_13. Finally we show how the LFV mu-e conversion and the
mu -> e gamma rates are strongly correlated in this model.
