The early production of heavy-flavour partons makes them an excellent probes for investigating the evolution of QCD systems. Jets tagged by the presence of a heavy-flavour hadron give access to the kinematics of the heavy partons and allow for comparisons of their production, propagation and fragmentation across different systems. Whilst traversing the quark-gluon plasma (QGP), charm and bottom quarks lose energy through interactions with the medium, at a different rate relative to light quarks and gluons. To constrain the energy loss in the QGP. the nuclear modification factor of D0-tagged jets is measured in the 0-10% most central Pb-Pb collisions at √SNN = 5.02 GeV/c s NN = 5.02 GeV / c . The properties of charm fragmentation are also investigated in pp collisions at √S = 5.02 GeV/c s NN = 5.02 GeV / c through measurements of the production and the momentum fraction of the D0 with respect to its jet.
