I am the principal privacy researcher at Brave Software, where I work on new ways to improve privacy and security on the Web, and to fix new threats to Brave browser users. I work under Hamed Haddadi, Ben Livshits, Brendan Eich and alongside a wonderful team of researchers, engineers and privacy experts.

I also co-chair PING, the group in the W3C that reviews spec proposals for privacy risks and concerns.

I also advise and support privacy groups and projects. Currently I am an advisor for the TIMBY project, a start up building private and secure reporting software for workers, journalists, and activists.

Before joining Brave, I worked on my PhD in the Computer Science department at the University of Illinois at Chicago in the BITS Lab, working under the kind and knowledgeable guidance of Chris Kanich.

Significant Programs and Code

  • Brave Browser PRs Features and bugfixes I've added to the Brave browser while working at Brave.
  • Fingerprinting Protections additional APIs hardening technique change Improved the technique used to block fingerprinting related Web API methods to reduce the impact on non-fingerprinting related code, and expanded the set of blocked Web API methods to cover five more, previously allowed, methods used for fingerprinting users.
  • Web API Manager Browser Extension firefox extension source WebExtension, cross-browser extension that allows users to improve their privacy and security online by controlling what browser functionality web hosts have access to. Web API functionality access controls can be defined in general, or on a per host level, and can allow, for example, only trusted hosts to have access to privacy-risky browser functionality like high resolution timers, WebGL and WebRTC.
  • CDF: Abstractions for Security Guarantees in Interactive Web Applications paper source Built client and server-side tools for implementing CDF, a document format for building dynamic, interactive web applications that provide increased security and privacy guarantees for users of commodity web browsers.
  • FormBug source A Firefox extension to make dealing and developing form based applications easier. I just maintain it now, but wrote it back when I was doing web development work.
  • Dijkstra's Algorithm (Objective-C implementation) cocoapods source Library to perform Dijkstra in Objective-C (for iOS and OSX).
