The neutrino mixing parameters are expected to have a renormalization group (RG) running effect in the presence of new physics. With mismatched energy scales between the neutrino production and detection processes, the oscillation probabilities are generally modified and become dependent on, not just the neutrino energy, but also the momentum transfer. The effect creates differences from standard oscillation and is present also for vanishing baseline.I will explore several works discussing the consequences of RG running on neutrino mixing parameters and current and future neutrino oscillation experiments. I will discuss how reactor experiments such as JUNO-TAO are capable of constraining the running of the CP-violation phase.  I will discuss the impact of RG running on the DUNE experiment where we propose a new $2$D statistical $\chi^2$ analysis as a smoking gun signal of RG running at DUNE's. Finally, I will explore the potential of combining future neutrino experiments to significantly increase the sensitivity to the running of all the neutrino mixing parameters.
