Mathematician #7 is Maryam Mirzakhani, the first (and to date only) woman to win the prestigious Fields Medal in Mathematics for her contributions to dynamics, topology and hyperbolic geometry. Mirzakhani was born in Tehran, Iran, and attended school there. She did not always want to study mathematics, but discovered a love for the subject in high school, winning two gold medals for Iran in the International Mathematical Olympiad. Mirzakhani was a professor of mathematics at Stanford University before she died in 2017.
Mirzakhani was a very private person, so there are not many videos or interviews of her on the Internet. However a film describing her life and work, Secrets of the Surface: the mathematical vision of Maryam Mirzakhani, was released in 2020. This Quanta magazine article also has a beautiful description of her work.
