  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. First results of a global analysis of the nuclear
modification factor of inclusive jets are presented where we extract medium
modified jet functions using a Monte Carlo sampling approach. We observe that
gluon jets are significantly more suppressed than quark jets. In addition, we
study the jet radius dependence of the inclusive jet cross section in heavy-ion
collisions and comment on a recent measurement from CMS. By considering for
example jet substructure observables it will be possible to test the
universality of the extracted medium jet functions. We thus expect that the
presented results will eventually allow for extractions of medium properties
with a reduced model bias.
