Mark L. Green, professor emeritus and co-founder/former Director of IPAM, was the invited speaker at the 2013 American Mathematical Society Congressional Briefing entitled "How Math Fuels the Knowledge Economy." His presentation encompassed how the role of the mathematical sciences has expanded dramatically in recent years, providing examples from a variety of dynamically growing industries including internet startups, biotech, film production, computer games, and individualized medicine. He also discussed the implications of these changes for training America's future workforce. Mark's presentation was based on the results of a recent National Academies/National Research Council study, "The Mathematical Sciences in 2025."

The AMS holds annual congressional briefings as a means to communicate information to policymakers. Speakers discuss the importance of mathematics research and present their work in layman's terms to Congressional staff as a way to inform Members of Congress of how mathematics impacts today's important issues.
