In collisions of ultra-relativistic heavy nuclei, the matter undergoes a phase transition into a deconfined state, known as Quark-Gluon Plasma (QGP). The QGP behaves as an almost perfect fluid, transforming the spatial anisotropies of the initial collision geometry into final-state particle momentum anisotropies, called anisotropic particle flow. Heavy-flavor quarks are created at the initial stage of the collision and experience the entire QGP evolution. Hence, the quarkonia, bound states of heavy-flavor quark-antiquark pairs, are unique probes of the QGP. The study of their anisotropic flow sheds light on the interaction of the heavy-flavor quarks with the QGP as well as on the basic QGP properties. In this seminar, selected recent studies of charmonium and bottomonium production, and in particular their anisotropic flow, in Pb-Pb and p-Pb collisions with the ALICE experiment at the LHC will be shown. The results will be compared to the corresponding measurements of light-flavor and open heavy-flavor particles and to the available theoretical models. The implications for our understanding of the QGP will be discussed. .
