Abstract:   The geometry of mapping class groups is very well understood thanks to the work of Masur, Minsky and others. The last couple of years have seen progress in a similar understanding of Out(F_n), the group of outer automorphisms of a free group. In the talk I will review the situation for both groups and point out some of the remaining challenges for Out(F_n).
