Jets are the experimental proxies for the hard sc attered partons\, convoluting both their perturbative and non-perturbative Quantum Chromodynamics (QCD) evolution. Depending on the collision system \, the outgoing partons can either traverse what we actually call a “QCD vacuum”\, as in deep inelastic scatterings (DIS) or proton-proton colli sions\, or a new\, highly complex state of matter - the quark-gluon plasma (QGP)\, produced in heavy-ion collisions (HICs). This medium evolves conc urrently with the hard partons\, further convoluting HIC jets with QGP-ind uced effects.Our research aims to use jet substructure to disentangle thes e effects and probe QCD across different environments and energy scales. W e employ substructure-based jet selections in electron-proton DIS to enhan ce sensitivity to non-perturbative effects\, moving towards constraining c urrently existing phenomenological models to describe hadronization. Furth ermore\, a detailed characterization of jet quenching\, i.e. the modificat ion of jets in the presence of a QGP\, has the potential to unlock a compr ehensive tomographic description of the QGP.
