Monodromy Inflation in SUSY QCD
  The discovery of a large tensor-to-scalar ratio by the BICEP2 experiment
points to large field excursions during inflation. One framework that predicts
large $r$ is monodromy inflation. While discussed mainly in the context of
string theory, the phenomenon can be illustrated and studied in the
well-understood framework of SUSY QCD with a large number of colors. We discuss
the requirements for viable inflation as well as various difficulties for model
building, including tunneling, tuning, and the species problem.
