The development of new theoretical tools and techniques for jet substructure has allowed us to experimentally access key aspects of the quark and gluon branching process.  Examples are the QCD splitting functions or the dead-cone effect in heavy quark fragmentation, recently measured in pp collisions at the LHC. 

I will review several of these results including the most recent measurement of the Lund plane. Such a plane, interesting as a tagging tool and as an observable, is a representation of the parton shower. Other groomed substructure measurements and prospects will be discussed.  

The extension of jet substructure to heavy-ion collisions is a recent active area of research. Recent measurements in Pb-Pb collisions of the groomed momentum balance or the groomed jet radius were designed to probe the microscopic structure of QCD matter at high temperature.
