  The drag and diffusion coefficients are studied within the framework of
Fokker-Planck dynamics for the case of a charm quark propagating in an
expanding quark-gluon plasma. The space-time evolution of the nuclear matter
created in the relativistic heavy-ion collision is modelled using MUSIC, a 3+1
D relativistic viscous hydrodynamic approach. The effect of viscous corrections
to the heavy quark transport coefficients is explored by considering scattering
processes with thermal quarks and gluons in the medium. It is observed that the
momentum diffusion of the heavy quarks is sensitive to the shear and bulk
viscosity to entropy ratios. The collisional energy loss of the charm quark in
the viscous quark-gluon plasma is analyzed.
