I work on Facebook’s Data Privacy team in London. I joined Facebook in 2014 following my bachelor’s degree at Cambridge University. I primarily work on building privacy-enhancing features, most notably Secret Conversations in Messenger, for which I lead security. Recently I have been investigating end-to-end encryption in group messaging, and have been collaborating with external partners from academia and industry to develop improved protocols for this.
