Heavy-flavour production and nuclear modification factor in Pb-Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}$=2.76 TeV with ALICE

The measurement of heavy-flavour production and nuclear modification factor in heavy-ion collisions provides insights into the mechanisms of parton energy loss in the hot and dense medium formed in these collisions. ALICE results on heavy-flavour decay electrons and muons and on D mesons are presented.
