The heavy quark system is an excellent probe for learning QCD dynamics at finite density. First, we discuss the properties of the J/ψ and D mesons at finite nucleon density. We discuss why their properties should change at finite density and then introduce an exact QCD relation among these hadron properties and the energy momentum tensor of the medium. Secondly, we discuss attempts to calculate the Charmonium-hadron total cross section using effective hadronic models and perturbative QCD. We emphasize a recent calculation, where the cross section is derived using the QCD factorization theorem. We conclude by discussing some challenges for SIS 200.
