Alexandra Henzinger

I am a postdoc at Stanford with Dan Boneh and an incoming Assistant Professor of Computer and Communication Sciences at EPFL, starting in Fall 2027. I completed my PhD in the PDOS and CSS groups at MIT, advised by Henry Corrigan-Gibbs. My email is ahenz@mit.edu.

My research builds computer systems that deliver privacy and security at scale. I work in computer security, systems, and cryptography. To learn more, see my thesis defense talk.
