  We study phenomenological implications of a radiative inverse seesaw dark
matter model. In this model, because neutrino masses are generated at two loop
level with inverse seesaw, the new physics mass scale can be as low as a few
hundred GeV and the model also naturally contain dark matter candidate. The
Yukawa couplings linking the SM leptons and new particles can be large. This
can lead to large lepton flavor violating effects. We find that future
experimental data on $\mu \to e \gamma$ and $\mu - e$ conversion can further
test the model. The new charged particles can affect significantly the $h \to
\gamma \gamma$ branching ratio in the SM. The model is able to explain the
deviation between the SM prediction and the LHC data. We also study some LHC
signatures of the new particles in the model.
