Maryam Mirzakhani — a 37-year-old mathematics professor at Stanford University — was awarded a Fields Medal. She is the first woman to win a Fields Medal – the most prestigious prize in mathematics. The Fields Medal is awarded every four years to between two and four scholars under the age of 40.
I find it interesting that Mirzakhani constantly doodles while she is thinking. She draws on huge pieces of paper on the floor. Her 3-year-old daughter, Anahita thinks that she is a painter.
Please see the Wikipedia article on Fields Medal for a list of the past and current winners.
