The production and space-time evolution of heavy quarks and J/psi in the quark gluon plasma is studied within the partonic transport model Boltzmann Approach to MultiParton Scatterings (BAMPS). An updated version of BAMPS is presented which allows interactions among all partons: gluons, light quarks and heavy quarks. Heavy quarks, in particular, interact with the rest of the medium via binary and radiative scatterings with a running coupling and a more precise Debye screening which is derived from hard thermal loop calculations. We compare our results of the elliptic flow and nuclear modification factor not only to experimental data of heavy flavor electrons at RHIC, but also to LHC data of heavy flavor electrons, muons, D mesons, and non-prompt J/psi. The latter two are in particular sensitive on the mass difference of charm and bottom quarks. Where no data is available yet, we make predictions for those observables. Furthermore, results on J/psi suppression are reported for central and non-central collisions, taking cold nuclear matter effects and the dissociation as well as regeneration of J/psi in the quark-gluon plasma into account.
