  The Linear Boltzmann Transport (LBT) model coupled to hydrodynamical
background is extended to include transport of both light partons and heavy
quarks through the quark-gluon plasma (QGP) in high-energy heavy-ion
collisions. The LBT model includes both elastic and inelastic
medium-interaction of both primary jet shower partons and thermal recoil
partons within perturbative QCD (pQCD). It is shown to simultaneously describe
the experimental data on heavy and light flavor hadron suppression in
high-energy heavy-ion collisions for different centralities at RHIC and LHC
energies. More detailed investigations within the LBT model illustrate the
importance of both initial parton spectra and the shapes of fragmentation
functions on the difference between the nuclear modifications of light and
heavy flavor hadrons. The dependence of the jet quenching parameter $\hat{q}$
on medium temperature and jet flavor is quantitatively extracted.
