I do research in cryptography, computer security, and theoretical computer science. Recently I have worked on building and analyzing systems for securely navigating encrypted data, constructing quantum-secure cryptography, and proving foundational results in theoretical cryptography.

In 2017 I found flaws in multi-user full-text search systems like Elastic. Amongst other consequences, my work showed how to access private repository data on GitHub. More information is available via our FAQ.

My publications are available online. See also my Google Scholar Citations page and my DBLP entry.
