  The measurement of D-meson production in heavy-ion collisions at LHC energy
provides insights into the mechanisms of interaction of charm quarks in the hot
and dense medium formed in these collisions. ALICE results on the D-meson
nuclear modification factor and azimuthal anisotropy in Pb-Pb collisions at
$\sqrt{s_{\rm NN}}=2.76$ TeV are presented.
