Recent work



I lead the Privacy Engineering team at Brave Software. We ship privacy features in the browser, conduct privacy reviews, work on advancing the state-of-the-art in adblocking while maintaining webcompat, and collaborate with the Research team to ship novel privacy interventions. I've previously worked on DNS, encrypted DNS, consent tooling and telemetry. I have an interest in privacy-respectful standards and am active in the IETF and W3C. I care about social implications of technology, and was an Internet of Rights fellow at ARTICLE 19, a UK-based human rights organization. I am currently on the Advisory Council of Open Tech Fund's Information Controls Fellowship. I recently wrote an essay on how privacy tech is increasingly dependent on centralized infrastructure in Meatspace Press's book "Eaten by the Internet".
