We implement a systematic effective field theory approach to the benchmarkprocess $\mu\to e \gamma$, performing automated one-loop computations includingdimension 6 operators and studying their anomalous dimensions. We obtain limitson Wilson coefficients of a relevant subset of lepton-flavour violatingoperators that contribute to the branching ratio $\mu\to e \gamma$ at one-loop.In addition, we illustrate a method to extract further constraints induced bythe mixing of operators under renormalisation-group evolution. This results inlimits on the corresponding Wilson coefficients directly at the high scale. Theprocedure can be applied to other processes as well and, as an example, weconsider also lepton-flavour violating decays of the $\tau$.
