Maryam Mirzakhani was an Iranian mathematician who made significant contributions to the theory of moduli spaces of Riemann surfaces and hyperbolic geometry. She was the first woman to be awarded the Fields Medal, which is often described as the "Nobel Prize of mathematics". Some of her major achievements included proving the prime number theorem for geodesics on hyperbolic surfaces and providing new insights into questions about the geometry of moduli spaces. She attended Sharif University of Technology and Harvard University and conducted research as a professor at Princeton University and Stanford University.
