One of the central questions in heavy-ion physics is understanding how jets propagate through strongly interacting matter. In this talk, I will present a first-principles analysis of the scale evolution of the two-point energy-energy correlator (EEC) in jets traversing nuclear matter. Energy correlators provide a particularly clean and model-independent probe of energy flow, making them powerful observables for isolating medium-induced dynamics. Using Soft-Collinear Effective theory with Glauber gluons, where partons interact with the medium via Glauber gluon exchanges, we compute the medium-modified jet functions at first order in opacity and derive the corresponding renormalization group equations. We perform the leading-logarithmic resummation and identify a kinematic regime in jet energy and angular separation where medium-induced corrections to the anomalous dimensions become directly measurable. Analytically, this manifests as a Coulomb logarithmic enhancement regulated by plasma screening. I will compare these results to p-Pb data from ALICE and present projections for O-O collisions, highlighting how energy correlators provide a systematically improvable way to constrain jet evolution in QCD matter.
