About Me
I work on better voting methods: building tools, analyzing election data, and explaining how systems like approval voting and proportional representation can make democracy more representative.
My background is in software engineering, which shapes how I approach democratic reform: as a systems problem where incentives, interfaces, data, and implementation details all matter.
I formerly chaired the Center for Election Science and have written about voting reform for publications including The Economist, Roll Call, and the San Francisco Chronicle.
Based in London, UK, I'm always open to connecting with interesting people. If you'd like to chat about technology, social choice theory, or engineering mentorship, feel free to book a 30 minute chat. I ask for a donation to the Center for Election Science to support their work.
