My knowledge of her research is limited to Wikipedia and the recent news articles. Based on that limited knowledge, I think her two major contributions were: 1. An asymptotic formula for the growth of the number of simple closed geodesics on a compact hyperbolic surface. 2. Proof for the conjecture that William Thurston's earthquake flow on Teichmüller space is ergodic. You explained point no. 1 in a simple way so that anyone could understand it. Thanks for that.
