  This paper reviews recent experimental results on hard probes in heavy-ion
collisions from the ALICE and STAR Collaboration. These studies include various
observables characterizing jet properties like nuclear modification factors,
recoil jet yields, di-jet and photon-jet energy imbalance, and the observables
characterizing jet properties like jet fragmentation function and jet shapes;
and measurements of high-$p_T$ charged hadrons from jet fragmentation and
triggered particle correlations will be highlighted.
