David Wu

02/18/2025 - David J. Wu, an assistant professor at the University of Texas at Austin, has received a Sloan Research Fellowship. The fellowship recognizes UT Austin as a leading public university and honors early-career researchers for their creativity and independent research. Wu specializes in cryptography, focusing on privacy-preserving systems and secure cloud computations that enable operations on encrypted data while ensuring confidentiality and authenticity.

03/03/2023 - A methodology developed by UT professors will allow the cost of verifying computations to be reduced by batching many separate arguments together. Brent Waters, a computer science professor and a co-author of the paper, was inspired to find a more efficient way to verify computations by refining techniques that had already come out over a decade ago.

08/04/2022 - Privacy has become increasingly valuable and rare as technology has become more closely integrated with our lives. Private information retrieval (PIR) protocols allow you to retrieve information through an encoded query while also protecting your personal information. Our current security standard online can be viewed as a “no-privacy baseline,” which means the vast majority of our online information retrieval isn’t protected by any of these protocols. Cryptographers like UT Computer Science professor David Wu are building innovative solutions that support this growing preference for online privacy.
