## Bio

Noah Giansiracusa, PhD in math from Brown University, is an associate professor of mathematics at Bentley University and visiting scholar at Harvard. After publishing the book **How Algorithms Create and Prevent Fake News** in July 2021 (about which Nobel Prize-winning economist Paul Romer 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 has gotten more involved in public writing/speaking and policy discussions concerning data-driven algorithms and their role in society. He's appeared on CNN live and BBC radio and written for Washington Post, Scientific American, TIME, and others, Noah is currently working on a second book, **Robin Hood Math**, exploring how people of all backgrounds—not just quants and techies—can use math to help navigate life. Noah is also cohost, with Gaurav Shah, of the AI in Academia podcast (https://www.buzzsprout.com/2313219).

*For the Fall 2024/Spring 2025 academic year, Noah will be a Visiting Scholar in the Institute for Rebooting Social Media at Harvard's Berkman Klein Center for Internet & Society, studying targeted advertising algorithms and the role they play in funding misinformation.*
