Relativistic heavy-ion collisions provide a unique opportunity to study the color-deconfined form of the QCD matter – quark-gluon plasma (QGP). Jets, produced at the primordial stage of nuclear collisions and then witnessing the whole evolution history of the QGP, are powerful tools for tomographing the QGP properties. In this talk, I will discuss how the interactions between jets and the QGP medium are affected by the jet flavor. The mass effect on parton splittings, known as the dead cone effect, is first investigated through the nuclear modification of different flavors of hadrons, and then extended to the substructures of different flavors of jets. In particular, both the magnitude and the extremum of the energy-energy correlator of jets are found sensitive to the jet flavor.
