Abstract

I outline the basic strategies for the computation of charm and bottom quark masses by means of lattice QCD, where particular emphasis is placed on the non-perturbative renormalization of the effective theory for the b-quark in heavy-light systems. A few selected results in the quenched approximation are reviewed, and the current status of extending these calculations to QCD with dynamical quarks is summarized.
