"What do we know about the shear-viscosity of QCD matter?"
        Abstract

                The success of ideal Relativistic Fluid Dynamics (RFD) in describing hadron
            spectra and elliptic flow at RHIC has led to a strong interest in the transport coefficients of QCD,
            in particular the shear- and bulk-viscosity as well as the shear-viscosity over entropy-density
            ratio /s.
                In my talk I will review our current state of knowledge on the shear viscosity of QCD
            matter at RHIC. In particular I will focus on the question whether low viscosity matter needs
            to be strongly interacting in the deconfined phase and on recent calculations of /s for a
            hadron gas in and out of chemical equilibrium.

    "Quantum Chromodynamics and High Energy Collisions"
            Abstract

                      QCD as a theory of strong interaction has been extremely successful
                 in interpreting the high energy scattering phenomena taking place at
                 a distance scale less than 1/10 fm. However, it faces many challenges
                 to explain the new and exciting phenomena observed in high energy
                 collisions involving large nuclei.
           
                    In this talk, I will briefly review the success of QCD and the limitation of
                 QCD calculations. I will identify the underline dynamics that contributes
                 to the nuclear dependence of cross sections in high energy nuclear
                 collisions. I will demonstrate the close connection between the observed
                 nuclear dependence and the partonic multiple scatterings in nuclear matter.
             
                    I will discuss new opportunities to explore QCD dynamics from high
                energy nuclear collisions and the role of hard probes in studying the
                properties of hot medium produced in relativistic heavy ion collisions.
