I am the senior 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.
