The strongly-interacting quark-gluon plasma (QGP) was one of the most important discoveries in relativistic heavy-ion collisions at RHIC and the LHC. Jet quenching, mainly characterized by parton energy loss and transverse broadening experienced by hard partons as they traverse and interact with the thermalized QGP, provides one of the important tools to study the novel properties of such hot and dense nuclear matter. In this talk, I will present some recent work on jet-medium interaction: the nuclear modification of jet rates, jet structures, and jet-related correlations.
