Maryam Mirzakhani has made several contributions to the theory of moduli spaces of Riemann surfaces.
Mirzakhani was awarded the Fields Medal in 2014 for "her outstanding contributions to the dynamics and geometry of Riemann surfaces and their moduli spaces." She died July 15, 2017.
I'm not expert in these areas of mathematics, but I am eager to know her main ideas and the importance of her results.
Can one draw a general picture of her works?
(Any expository reference will be appreciated).
