I’m a journalist and software developer based in Portland, Oregon. I've spent the last decade working as a reporter, editor, and programmer in newsrooms and nonprofits in the U.S.

During the 2015-16 academic year I was a John S. Knight Journalism Fellow at Stanford University researching ways to make complex document processing affordable to reporters. I’m especially interested in turning unstructured images into data, and building tools to mine actionable news tips from some of the dullest corners of the web. You can read more about that project here.

Previously I was editorial engineer at The Sunlight Foundation, where I worked extensively on campaign finance, TV ad disclosure, and House and Senate expenditure reporting. Prior to that I was Director of Computer-Assisted Reporting, at the Investigative Reporting Workshop, a nonprofit at American University. I also reported for several newspapers in Pennsylvania.

Long ago I was an undergraduate physics major, and got my first real taste of programming hacking on C++ code to look at engineering runs at LIGO Hanford.
