Research [publications, PhD thesis] I am interested in data access and deletion infrastructure.

Me giving a talk on cookie infrastructure, and another on group messaging and another on deletion; Totally Accurate Register Coverage. My Erdos number is four (one, two, three, four) if you allow conferences. I guest-review for Black Hat.
Code I write code for a living, mostly related to user privacy. I've worked on data access and portability tools, deletion, cookies, task federation, and incident management, among many other projects. I'm currently at m e t a where I help to make the Privacy Review process more reliable and automated. I'm at home working with legal and policy folks, and translating between code and regulatory requirements.
