  We study the medium response to jet evolution in the quark-gluon plasma
within the JETSCAPE framework. Recoil partons' medium response in the weakly
coupled description is implemented in the multi-stage jet energy-loss model in
the framework. As a further extension, the hydrodynamic description is
rearranged to include in-medium jet transport based on a strong-coupling
picture. To interface hydrodynamics with jet energy-loss models, the
hydrodynamic source term is modeled by a causal formulation employing the
relativistic diffusion equation. The jet shape and fragmentation function are
studied via realistic simulations with weakly coupled recoils. We also
demonstrate modifications in the medium caused by the hydrodynamic response.
