The string/gauge theory correspondence has turned out to be a surprisingly effective tool to compute dynamical properties of strongly-coupled gauge theories at finite temperature. Progress has recently been made in trying to understand the physics of mesonic resonances which seem to survive rather deep into the phase where gluons are deconfined. I will discuss the string theory models which underly these calculations and the results they predict for the dissociation of heavy-quark mesons in a quark-gluon plasma. (based on hep-th/0606195)
