I shall describe the asymptotic geometry of the mapping class
group, in particular its tree-graded structure and
its equivariant embedding in a product of trees.
This can be applied to study homomorphisms into mapping class
groups defined on groups with property (T) and on lattices in semisimple groups.
The talk is based upon two joint works with J. Behrstock, Sh. Mozes and M. Sapir.
