Academic   I study security protocols, particularly the ones that people really use on the modern Internet. I'm interested in Signal, Certificate Transparency, TextSecure/Axolotl, TLS 1.3, the Tamarin prover, WebRTC, and other such things. I'm an Oxford Cyber Security CDT student, supervised by Cas Cremers.

newWe wrote On Ends-to-Ends Encryption, looking at improving the security of group messaging protocols while still respecting the constraints of modern asynchronous protocols like Signal.

Industry   Past jobs include full-time work at GSA Capital and internships at Facebook (upcoming), Google, Red Gate and Cantab Capital. I guest-reviewed for Black Hat USA this year.

Posts   I sometimes post long-form and short-form things.

Internet   You can find me on many other websites. I used to spend a lot of time on Stack Overflow but these days it's Github if anything. The usual collection of profiles are where you'd expect them on Facebook, MetaFilter, and LinkedIn. I listen to music through Spotify and motivate myself with Beeminder. FollowUpThen snoozes my emails, forecast.io handles weather, and Splitwise organises bills.

Contact me via email, via keybase if you are that way inclined.
