I’m a hacker-journalist, working 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 including healthcare data breaches, wasteful military spending, and cybersecurity. I also do a bit of devops, managing parts of our web app infrastructure, migrating our site to encrypted HTTPS-only, and providing a Tor hidden service to our readers. Before joining ProPublica full-time, I was a Knight-Mozilla OpenNews Fellow.
I’m very interested in cybersecurity, online privacy, data collection, and anonymity: in addition to the aforementioned ProPublica Tor hidden service, I’m also the creator of Onion Browser, an open-source, privacy-enhancing web browser for iOS which uses the Tor network. I frequently speak at conferences and conduct workshops to teach people how to protect themselves online.
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. Tabula, received a grant from the Knight Foundation and was a finalist for the 2014 Online News Association Award for Technical Innovation in the Service of Digital Journalism. CivOmega (as in, "Wolfram Alpha for civic data") received a grant from the Sunlight Foundation.
In addition to investigative reporting and developing tools for readers and journalists alike, I like to share practical knowldege with others, by open-sourcing work and training others: I've participated in many conference panels, talks, and workshops teaching others to use various data analysis tools and also teaching people about threat modeling and encryption tools that can help protect themselves, their work, and their friends/family/colleagues/sources.
A small selection of projects and speaking engagements are listed below.
You can find a thorough list of reporting and news apps at ProPublica.
Many more open-source projects and snippets are at GitHub.
