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