Maryam Mirzakhani, groundbreaking mathematician and Fields Medal winner, dies at 40

Maryam Mirzakhani, who in 2014 became the first woman awarded the prestigious Fields Medal for mathematics, has died at the age of 40.

The world-renowned Iranian mathematician and Stanford professor died from breast cancer at a hospital in the United States.

“Maryam is gone far too soon, but her impact will live on for the thousands of women she inspired to pursue math and science,” Stanford President Marc Tessier-Lavigne said in a statement. “Maryam was a brilliant mathematical theorist, and also a humble person who accepted honors only with the hope that it might encourage others to follow her path.”

Her friend Firouz Michael Naderi, an Iranian-American NASA scientist, said on Instagram, “A light was turned off today. It breaks my heart…gone far too soon.”

Born in Tehran in 1977, Mirzakhani won two international math awards as a teenager. Despite an auspicious start, she said that she had no intention of pursing mathematics. She liked to read and thought that maybe she would become a writer.

“My most exciting pastime was reading novels; in fact, I would read anything I could find,” she said in a 2014 interview with The Guardian.

It was at Sharif University of Technology in Iran, where she received her Bachelor of Science, that she discovered her passion for mathematics.

“The more I spent time on mathematics, the more excited I became,” she told The Guardian.

Mirzakhani completed her PhD at Harvard in 2004, then accepted positions as a research fellow at the Clay Mathematics Institute and an assistant professor at Princeton, accruing awards and acclaim along the way. In 2008, at 31, she became a professor at Stanford.

And then, in 2014, she received the highest honor in mathematics: 80 years after the award was established, Mirzakhani became the first woman to win the Fields Medal. She was also the first Iranian to receive the prize, which is given every four years to exceptional mathematicians under the age of 40.

According to the awarding committee, Mirzakhani’s genius came from her “rare combination of superb technical ability, bold ambition, far-reaching vision, and deep curiosity.”

She won the prize for a 172-page paper on the trajectory of a billiards ball around a polygonal table that has been hailed as a “titanic work” and the “beginning of a new era” in mathematics. Mirzakhani studied the complexities of curved surfaces such as spheres, doughnut shapes and hyperbolas. She said in interviews that she liked the interdisciplinary connections and implications of her work.

“I find it fascinating that you can look at the same problem from different perspectives and approach it using different methods,” she said.

Mirzakhani, who described herself as a slow mathematician, was drawn to big, difficult questions in her field, a trait that made her a revered figure within the mathematics community.

In 2014, she told Quanta Magazine, a science publication, that she thought about mathematics in pictures, doodling her ideas on giant sheets of paper scattered across her office. A colleague speculated that perhaps she organized her thoughts like this because the “problems she is working on are so abstract and complicated, she can’t afford to make logical steps one by one but has to make big jumps.”

As a professor and scholar, Mirzakhani’s pictures helped her write stories with her math. In a way, she told Quanta, working on mathematics is a lot like writing a novel.

“There are different characters, and you are getting to know them better,” she said. “Things evolve, and then you look back at a character, and it’s completely different from your first impression.”

She is survived by her husband, Jan Vondrák, and their daughter, Anahita.
