The bound states of a heavy quark and antiquark (c\c, b\b) are\nideal probes to explore the quark-gluon plasma created in relativistic\nheavy-ion collisions at the RHIC and LHC. Not only have they become\nexperimentally accessible with high precision but also efficient tools, so\ncalled effective field theories (EFT) have been developed to treat them\ntheoretically. Here we present recent progress in understanding the in-medium\nbehavior of heavy-quarkonium with the help of EFT's combined with\nnon-perturbative and first principles simulations in lattice QCD. In particular\nwe discuss computations of heavy quarkonium spectral functions with the help of\nBayesian unfolding methods and the physics we can extract from them.\nLimitations and the underlying assumptions of the used approaches are pointed\nout.\n
