Cynthia Dwork uses theoretical computer science to place societal problems on a firm mathematical foundation. She was awarded the Edsger W. Dijkstra Prize in 2007 in recognition of some of her earliest work establishing the pillars on which every fault tolerant system has been built for a generation (Dwork, Lynch, and Stockmeyer, 1984).

Her contributions to cryptography include the launching of non-malleable cryptography, the subfield of modern cryptography that studies -- and remedies -- the failures of cryptographic protocols to compose securely (Dolev, Dwork, and Naor, 1991).  She is a co-inventor of the first public-key cryptosystem based on lattices, the current best bet for cryptographic constructions that will remain secure even against quantum computers (Ajtai and Dwork, 1997). More recently, Dwork spearheaded a successful effort to place privacy-preserving analysis of data on a firm mathematical foundation.  A cornerstone of this effort is the invention of Differential Privacy (Dwork, McSherry, Nissim, and Smith, 2006, Dwork 2006), now the subject of intense activity in across many disciplines and recipient of the Theory of Cryptography Conference 2016 Test-of-Time award. With its introduction into Apple's iOS 10 (2016) and Google's Chrome browser (2014), differential privacy is just now beginning to be deployed on a global scale. 

Dwork was educated at Princeton and Cornell.  She received her BSE (with honors) in electrical engineering and computer science at Princeton University, where she also received the Charles Ira Young Award for Excellence in Independent Research, the first woman ever to do so.  She received her MSc and PhD degrees in computer science at Cornell University. 

Dwork is a member of the US National Academy of Sciences and the US National Academy of Engineering, and is a fellow of the ACM, the American Academy of Arts and Sciences, and the American Philosophical Society.
