*Extracting Scattering and Resonance Properties from the Lattice*

As JLab completes its 12 GeV upgrade, the coming years are expected to 
bring major developments in our
understanding of the strong force. To get the most out of upcoming 
experiments, it is crucial to have solid
theory predictions, based in the underlying theory of QCD. Here the well 
established methods of Lattice QCD
should play a key role. However, numerical Lattice QCD calculations are 
necessarily performed in a finite volume
and with Euclidean time and for scattering and transition amplitudes 
these constraints have important consequences.
It is not possible to directly access the desired observables from the 
numerically determined correlators. Nonetheless,
great progress has been made by using finite volume as a tool rather 
than an artifact, and deriving non-perturbative
relations between the finite- and infinite-volume theories. I will 
review recent developments in this work with particular
focus on three-hadron final states.
