Abstract:	Let Mod(S) be the mapping class group of a closed connected orientable surface of genus at least 2. Let G be a non-elementary subgroup of Mod(S) with finite Bowen-Margulis measure. In this talk, I will explain how to use recent results on conformal density to deduce an asymptotic growth formula for G with respect to the Teichmuller metric which covers the classical counting result for Mod(S). This talk is based on joint work in progress with Ilya Gekhtman.
