    Reconstructed jets in heavy ion collisions have become an effective and revealing way to probe the quenching and modification of high-energy partons and answer fundamental questions about the nature of the quark gluon plasma. Following the success of single-particle measurements and two-particle correlations in Au+Au collisions at RHIC, experiments at the LHC have begun a comprehensive program of differential jet measurements in Pb+Pb collisions. Since knowledge of the quenching dynamics at RHIC energies may be crucial in understanding the temperature dependence of the plasma properties, I will discuss how the progress in jets in HI collisions could be applied to a jet physics program at RHIC with the sPHENIX detector. Furthermore, the recent p+Pb run at the LHC and the installation of the MPC-EX at PHENIX will provide a rich set of opportunities to test for signals of saturation, broadening and other cold nuclear matter effects using jets and photons. Specifically, the p+Pb data could help shed light on the large centrality-dependent differences in high-pT jet production observed in d+Au collisions.
