I am the Morris M. Doyle Centennial Professor of Public Policy in Stanford University's Department of Political Science, Senior Fellow at the Hoover Institution, and Co-Director of the Democracy and Polarization Lab.  My research focuses on elections, representation, artificial intelligence, and data science.  

I serve as an advisor for Home Key, an AI-based real estate start up. I also regularly testify as an expert witness in litigation on election administration and allegations of voter fraud. Previously, I worked as a consultant for Meta, Inc, focusing on issues at the intersection of politics and social media.
