I’m a professor of computer science at the University of Michigan and Director of Michigan’s Center for Computer Security and Society. <a href="https://jhalderm.com">My research</a> spans software security, network security, privacy, anonymity, electronic voting, and censorship resistance. I've uncovered problems in e-voting systems in the U.S., Estonia, India, and Australia. I was part of the teams that discovered the TLS <a href="https://weakdh.org">Logjam</a> and <a href="https://drownattack.com">DROWN</a> vulnerabilities. My recent projects include <a href="https://letsencrypt.org">Let's Encrypt, <a href="https://decoyrouting.com">Decoy Routing</a>, <a href="https://zmap.io">ZMap</a>, and <a href="https://censys.io">Censys</a>.
