### Description

We study charmonium physics in heavy-ion collisions within the framework of the non-equilibrium transport model UrQMD. Using this model we compute different heavy quark observables like the nuclear modification factor $R_{AA}$, high $p_T$ suppression and the elliptic flow $v_2$. The UrQMD approach includes explicit interactions of the charmed particles with the surrounding medium. Different cross sections for charmonium dissociation and charmonium recombination by D-Mesons are tested at SPS, RHIC and LHC energies. We show that these results are in good agreement with measurements at the different collision energies.
