I have retired amicably from Google after exactly ten years and am pursuing my own interests, which are currently focused on reading, writing, smallholding, and avoiding travel. For tech security, privacy and policy I'm keeping connected in a minor way by advising on the Deterrence of Deception research programme.
My earlier publications can be found here: Why Johnny Can't Encrypt, and
technical report. Making Security Usable (PhD dissertation,
2004) or just the abstract.
