  In this article we wish to present a new method to obtain spectral functions
at finite temperature and density from the Functional Renormalization Group
(FRG). The FRG offers a powerful non-perturbative tool to deal with phase
transitions in strong-interaction matter under extreme conditions and their
fluctuation properties. Based on a thermodynamically consistent truncation we
derive flow equations for pertinent two-point functions in Minkowski
space-time. We demonstrate the feasibility of the method by calculating mesonic
spectral functions in hot and dense hadronic matter using the quark-meson model
as a simple example.
