## Bio

Noah Giansiracusa (PhD in math from Brown University) is an assistant professor of mathematics and data science at Bentley University. Noah's research interests include algebraic geometry (the abstract study of systems of polynomial equations and their solutions), machine learning (especially topological and geometric data analysis), empirical legal studies, phylogenetics, and misinformation. Noah is the author of "How Algorithms Create and Prevent Fake News," about which Paul Romer, Nobel Laureate and former Chief Economist of the World Bank, said "It's a joy to read a book by a mathematician who knows how to write... There is no better guide to the strategies and stakes of this battle for the future." Noah's public writing appears in Wired, Slate, and Fast Company, he's been interviewed in TechCrunch and Tech Policy Press, and he has been quoted in Washington Post, Financial Times, Forbes, U.S. News, Agence France-Presse (AFP), and New Delhi TV.
