I write a weekly newsletter called Free Systems: Experiments to Preserve Liberty in an Algorithmic World.

I run the Free Systems research lab, which is housed across the Hoover Institution and Stanford GSB. We focus on understanding how to preserve human liberty in an increasingly algorithmic world. We build in public, running governance experiments, stress-testing frontier AI models, and prototyping tools to help ordinary people keep a real say in how AI and online platforms are governed.

For years I have used large-scale data and econometric and machine-learning methods to study how we organize collective decision-making and design democratic systems of governance, for both the online and physical worlds. That work has increasingly turned to artificial intelligence: how AI systems shape political information and behavior, how they can be governed, and how AI itself can be used to design and test better systems of governance.

I am a research advisor to the a16z crypto research team, where I study decentralized governance and help online platforms to design their governance systems. I am also an advisor to Forum AI. Previously, I spent 8 years as an advisor at Meta Platforms, working on a wide range of governance and strategic issues in Global Affairs and, later, in the Wearables Business Group.
