My research lies at the intersection of computer security and distributed systems. Topics that interest me include software and network security, data privacy, anonymity, and electronic voting. Recently, I've spent much of my time trying to find new ways to protect the security and privacy of users of “cloud hosted” services. I'm also particularly interested in the interaction between computer security, law, and public policy. I'm also a member of the Computer Science Department's CERES Center for Unstoppable Computing.
Before arriving at Chicago, I was a postdoc at the University of Pennsylvania's Department of Computer and Information Science where I was affiliated with the Security Laboratory and I worked with Jonathan Smith and Andreas Haeberlen. Before that, I received my Ph.D. from Princeton University's Computer Science Department where I was affiliated with the Security Research Group and the Center for Information Technology Policy. My advisor was Ed Felten, and I worked with Mike Freedman.
