Title:	Twisted Alexander polynomials, hyperbolic geometry, and knot genus
Abstract:	A hyperbolic knot has an associated Alexander polynomial that is twisted by the holonomy representation of the hyperbolic structure. I will discuss properties of this invariant and give evidence that it is extremely good at detecting knot genus and fibering.  This is joint work with Stefan Friedl and Nicholas Jackson.
