Overview of heavy flavor results at RHIC and the LHC
Heavy flavor quarks offer unique insights to the properties of the strongly coupled Quark-Gluon Plasma (QGP) created in heavy-ion collisions. Recently, precision heavy flavor measurements are made available thanks to the advanced detector technology and high luminosity collisions provided by RHIC and the LHC colliders. In this talk, I will review these recent experimental achievements and discuss physics we learn in terms of QCD in finite temperature regions. I will also highlight some issues and challenges, and present future experimental prospects with heavy flavor measurements at RHIC and the LHC.
