Cody Cook is an assistant professor in Yale’s Department of Economics who studies affordable housing, congestion pricing, and urban inequality, translating policy questions into rigorous empirical work. A Stanford Ph.D. in Economics with earlier training at the University of Chicago, he brings 11 years of experience combining academic research and industry data science. He spent several years on Uber’s research team (Ubernomics) and at TGG, turning economic insights into large-scale analyses and policy-relevant experiments. Cody is also an active open-source contributor — his backend work on projects like uber/kraken and pantsbuild/pants improved TB-scale data distribution and build caching — a technical depth he leverages to run production-grade empirical work. Based in San Francisco, he blends production engineering skills with economic theory to make urban policy research operational at scale.
