IRNA � The UN Resident Coordinator in Iran on Saturday expressed sadness over the death of the well-known Iranian mathematician and prayed for her peace.

�Sad to learn about the passing away of Maryam Mirzakhani - the intelligent Iranian daughter, wife, mother, professor,� Gary Lewis wrote in his twitter account.

NASA Iranian scientist Firooz Naderi announcing Mirzakhani�s death wrote in a tweet, �A light was turned off today. It breaks my heart� gone far too soon.�

May her eternal soul rest in peace, the UN officer added.

In 1994, Mirzakhani won a gold medal in the Hong Kong International Mathematical Olympiad, to be the first female Iranian student to have received a gold medal. In the 1995 Toronto International Mathematical Olympiad, she became the first Iranian student to receive a perfect score and to win two gold medals.

She obtained her BSc in mathematics (1999) from Sharif University of Technology, Tehran. She went to the US and got a PhD from Harvard University in 2004.

Mirzakhani (b. May 3, 1977) was diagnosed with breast cancer in 2013, a year before she set the record of the first ever woman to win the prestigious Fields Medal.
