Shai Halevi research covers most aspects of cryptography: from public-key to symmetric cryptography, constructions, cryptanalysis, and foundational work. It includes breakthrough results on multilinear maps and obfuscation, advances in the theory of homomorphic encryption, and the implementations of both the HElib homomorphic encryption library and of branching-program obfuscation. Shai is a Fellow and a board member of the International Association of Cryptologic Research (IACR). He is the recipient of the 2017 SIGSAC Outstanding Innovation Award, the Eurocrypt 2013 best paper award and the IBM Pat Goldberg best-paper awards in 2004, 2012 and 2013. He is the chair of the steering committee for the TCC conference, and was program (co)chair of ACM-CCS 2016, Crypto 2009, and TCC 2006. Shai obtained his Ph.D. in Computer Science from MIT in 1997 and has authored more than 100 publications with over 20,000 citations. Prior to joining the Algorand Foundation, he was a researcher at IBM Research.
