There is no external force more influential on human behavior than culture — full stop.

Marcus studies cultural contagion and how it manifests in our consumption, organizational dynamics, and society at large. He bridges the academic-practitioner gap as a clinical professor at the Ross School of Business, University of Michigan and as the former head of strategy at Wieden+Kennedy New York.

Before advertising, he led iTunes + Nike sports music at Apple and ran digital strategy for Beyoncé. He's the author of the bestselling book For The Culture — examining how culture shapes human behavior and how to use it to move people.
