Joseph A. Calandrino

I am the Research Director in the Federal Trade Commission's Bureau of Consumer Protection. My research focus is at the intersection of computer science with consumer protection.

I received my doctorate in Computer Science from Princeton University, where I was advised by Ed Felten and was affiliated with the Center for Information Technology Policy. My graduate research focused on the privacy and security implications of emerging technologies, from electronic voting systems to recommender systems. I hold masters degrees in Computer Science from Princeton and the University of Virginia. I received my BS from the University of Virginia in Computer Science and Mathematics.
