In Fall, 2018, I will join the Computer Science Department at The University of Texas at Austin. I look forward to working with talented graduate students and undergraduate Turing Scholars—please apply!

Professional Activities

I am co-program chair (with Christopher Kruegel) of IEEE Security and Privacy (“Oakland”) 2019.

I am co-program chair (with Alexandra Boldyreva) of Crypto 2018.

In February, 2016, I submitted, along with other security researchers, a brief of amici curiae in support of Apple, organized by Stanford’s Center for Internet and Society.

In January, 2014, I signed an open letter from US researchers in cryptography and information security: masssurveillance.info.

Brief Biography

Hovav Shacham’s research interests are in applied cryptography, systems security, privacy-enhancing technologies, and technology policy. Shacham was a student at Stanford and a postdoctoral fellow at the Weizmann Institute. From 2007 to 2018, he was on the faculty at the University of California, San Diego. He received the 2017 ACM CCS Test-of-Time Award for his 2007 paper that introduced return-oriented programming. Shacham took part in California’s 2007 “Top-to-Bottom” voting systems review and served on the advisory committee for California’s 2011–13 post-election risk-limiting audit pilot program. His work has been cited by the Federal Trade Commission, the National Highway Traffic Safety Administration, and the RAND Corporation.
