Abstract: 

We present a non-perturbative method to obtain spectral functions at finite temperature and density from the Functional Renormalization Group (FRG). Flow-equations in Minkowski space-time are obtained from their Euclidean counterparts via an analytic continuation procedure on
the level of these flow-equations. To demonstrate the feasibility of this method, we compute mesonic spectral functions of effective QCD-models along the phase diagram of these models.
