We study the evolution of heavy quarkonium states with temperature in a Quark Gluon Plasma (QGP) in terms of the in-medium QQ-bar T-matrix obtained from a reduced Bethe-Salpeter equation. The interaction potential is extracted from finite-temperature lattice QCD calculations of the QQ-bar internal energy. The quarkonium spectral functions and Euclidean correlators are sensitive to the interplay of bound states and the (non-perturbative) continuum, and to heavy-quark in-medium single-particle properties. Further applications in the heavy-light quark and pure gauge sectors are addressed.
