I am currently a product manager at Google, working on adding value to Chrome Security. Despite this, I identify both as an engineer and security researcher. I cofounded Censys, an attack-surface management security startup. I left Censys after their Series A. They’ve since raised a Series B Series C! I was employee #2 at Nametag. I’m also a core contributor to the ZMap open-source project.

I have a PhD from the University of Michigan. I defended in 2018. My advisor was J. Alex Halderman. My research focus was using Internet-wide scanning to measure how cryptography is used on the Internet. It led to the discovery of the Logjam and DROWN attacks on TLS, and the creation of Censys.

In 2021, I accidentally started the “Security. Cryptography. Whatever.” podcast with Deirdre Connolly and Thomas Ptacek.
