Ariel Feldman
Software Engineer at Google
About me [CV]
I'm a software engineer at Google working on cloud key management and trusted execution environments. I work on systems security, especially on enabling users to outsource computation and sensitive data to third parties without having to fully trust them. I'm particularly interested in problems that intersect with law and public policy, such as electronic voting security, which has been the subject of some of my prior work.
Previously, I was a tenure-track assistant professor of Computer Science at the University of Chicago where I taught these courses and worked with these amazing students.
