In this minicourse I will describe moduli spaces of graphs and explain how they can be used to study the cohomology of automorphism groups of free groups. Topics may include homological stability, the construction of nontrivial cycles, the relationship with the cohomology of certain Lie algebras of derivations and the structure at infinity of the spaces.
