We review a recently proposed phenomenological framework to establish the notions of QCD factorization and universality of jet cross sections in the heavy-ion environment. We present first results of a global analysis of the nuclear modification factor for inclusive jets and extract medium modified jet functions using a Monte Carlo sampling approach. We observe that gluon jets are significantly more suppressed than quark jets, including for example jet substructure observables which will eventually allow us to test universality. We study the jet radius dependence of the inclusive jet cross section in heavy-ion collisions and comment on a recent measurement from CMS. We expect that the presented results will eventually allow for extractions of medium properties with a reduced model bias.
