  Heavy quarks, produced in hard parton scatterings in the early stage of
ultra-relativistic heavy-ion collisions, are ideal probes to investigate the
properties of the Quark--Gluon Plasma (QGP) produced in such collisions.
Measurements of heavy-flavour jets can provide constraints on energy-loss
models. In particular, they add information on how the radiated energy is
dissipated in the medium. Studies of angular correlations between heavy-flavour
and charged particles allow us to characterize the heavy-quark fragmentation
process and its possible modification in a hot nuclear matter environment. This
manuscript will focus on the latest results on heavy-flavour jets and D-meson
correlations with charged particles studied with the ALICE detector in pp,
p--Pb and Pb--Pb collisions.
