Irit Dinur (Hebrew: אירית דינור) is an Israeli computer scientist. She is professor of computer science at the Weizmann Institute of Science.[1] Her research is in foundations of computer science and in combinatorics, and especially in probabilistically checkable proofs and hardness of approximation.[2]


Irit Dinur earned her doctorate in 2002 from the school of computer science in Tel Aviv University, advised by Shmuel Safra; her thesis was entitled On the Hardness of Approximating the Minimum Vertex Cover and The Closest Vector in a Lattice.[3] She joined the Weizmann Institute after visiting the Institute for Advanced Study in Princeton, New Jersey, NEC, and the University of California, Berkeley.

Dinur published in 2006 a new proof of the PCP theorem that was significantly simpler than previous proofs of the same result.[4]

Awards and recognition

In 2007, she was given the Michael Bruno Memorial Award in Computer Science by Yad Hanadiv.[5] She was a plenary speaker at the 2010 International Congress of Mathematicians.[6] In 2012, she won the Anna and Lajos Erdős Prize in Mathematics, given by the Israel Mathematical Union.[7] She was the William Bentinck-Smith Fellow at Harvard University in 2012–2013.[8] In 2019, she won the Gödel Prize for her paper "The PCP theorem by gap amplification".[9]
