Hall is a professor of political economy at Stanford Graduate School of Business, with a joint appointment in the Stanford University Political Science Department. He is a senior fellow at the Stanford Institute for Economic Policy Research, and for the 2022–2023 academic year, he is a senior fellow by courtesy at the Hoover Institution. Along with his academic research, Hall works at the intersection of tech and society, advising tech companies, startups, blockchain protocols, and others on how to make better and more socially legitimate decisions, products, and policies. This includes work to design and build governance systems — systems of algorithms, rules, rule-making procedures, appeals processes, and other institutions that shape how people and communities use tech products and how they affect society.
