By day, I’m a news applications developer at ProPublica. I spend most of my time working on investigative journalism — creating news applications, performing data analyses, and reporting on a variety of topics from healthcare to cybersecurity. Before joining ProPublica, I was a Knight-Mozilla OpenNews Fellow and previously worked at The Spokesman-Review regional newspaper in Spokane, Washington.

I’m very interested in cybersecurity, online privacy, data collection, and anonymity: I’m also the creator of Onion Browser, an open-source, privacy-enhancing web browser for iOS which uses the Tor network.

I also do a lot of work in the "civic hacking" space, especially around open data and open government issues. I'm a core developer of several open-source tools that help citizens use public data and help governments work more transparently; several of these projects have received grant funding from the Knight Foundation and Sunlight Foundation.

I often work on training and resources for journalists: I've participated in several conference panels, talks, and workshops teaching others to use various data analysis tools and also teaching journalists threat modeling and encryption tools that can help protect their work and their sources.

See a list of projects and talks/workshops below.
