Dinur has worked as a lecturer and researcher for the
Institute for Advanced Study in
Princeton, New Jersey,
NEC, the
Hebrew University of Jerusalem, and the
University of California, Berkeley. From 2007 to 2024, Dinur was a professor at the Weizmann Institute. The PCP theorem, concerning
probabilistically checkable proofs, states that some mathematical proofs can be checked with a high success rate just by writing them in PCP form and then randomly checking whether a few steps are true. Dinur creatively used
expander graphs to prove the theorem via geometric means, and this connected the intuition behind the PCP theorem to other fields of math. Dinur's work on
differential privacy has been incorporated into the
2020 U.S. census and is used by some large companies in order to preserve the privacy of individual users while analyzing their collective data. Dinur has also researched
locally testable codes, expander graphs in higher dimensions, and optimization. ==Awards and recognition==
