I am a Ph.D. candidate in Computer Science and Engineering at the University of Michigan, where my research focuses on computer security and privacy. I am advised by Prof. J. Alex Halderman and funded by an NSF Graduate Research Fellowship and the Post-9/11 GI Bill.

My dissertation attempts to understand the world's most powerful attackers, including nation-state adversaries such as NSA and GCHQ. By analyzing their known operations and behaviors, we can better understand how to detect attacks and build systems and protocols to protect against well resourced adversaries.

My work helped explain how intelligence agencies may be able to defeat widely used cryptography. In other work, I showed that widely used TLS crypto shortcuts could be exploited to retrospectively decrypt connections to many of the most popular sites. I studied how foreign adversaries could compromise Internet voting to interfere with elections, and I've investigated HTTPS interception and FTP vulnerabilities.

My research has been covered and cited by The Wall Street Journal, The Washington Post, Ars Technica, The Guardian, US-CERT, NIST, FBI Cyber Division, and Playboy, and it has been referenced multiple times during the development of TLS 1.3. I contribute to open-source projects such as Censys and ZMap, and I occasionally help find RFC bugs during job interviews.
