        Summary
        Recent analysis of heavy ion collisions has shown clear signs of a temperature dependence of the shear viscosity to entropy ratio. However, it is very difficult to compute the shear viscosity theoretically in strongly coupled plasmas using traditional methods. One alternative method is to use holographic correspondence. However, the standard holographic computation yields a universal value for the shear viscosity to entropy ratio that is independent of temperature. In this thesis, we modify the bottom-up QCD-like holographic theories with the goal of matching the T-dependence of the shear viscosity to entropy ratio to the one observed for quark-gluon plasma. For this, we use the Bayesian analysis of heavy ion collisions.
