Quasisymmetries are an important class of homeomorphisms related to analysis on metric spaces and quasiconformal geometry.  In this talk, I will introduce quasisymmetries and outline a theory of quasisymmetries for finitely ramified fractals, with applications to fractals such as generalized Sierpinski triangles and Julia sets of hyperbolic polynomials.  This is joint work with Bradley Forrest.
