A promising approach to study the properties of deconfined QCD matter (e.g. the quark-gluon plasma) is to analyze its interactions with jets. Presently, experiments probing this new state of matter in heavy-ion collisions are being performed at RHIC and LHC. A recent theoretical development involves the application of effective field theories for a more systematic approach to the calculation of jet-medium interactions. In this talk, the basic ideas will be introduced and some current issues are discussed.
