Developments in hard probes of heavy ion collisions

In this talk, I will provide a general overview of the status, interpretation, and future prospects for hard probe measurements of ultrarelativistic heavy ion collisions. In recent years, existing hard probes measurements have reached new levels of precision and systematic control, while entirely new channels and techniques have also been developed. These include single and di-hadrons, fully reconstructed jets, electroweak boson + jet pairs, jet structure and substructure, and heavy flavor production. I will discuss what these measurements reveal about the nature of the Quark Gluon Plasma at RHIC and the LHC, and give some thoughts on future prospects.
