He is best known for his work on stereotype threat and its application to minority student academic performance. His earlier work dealt with research on the self (like self-image and self-affirmation) as well as the role of self-regulation in addictive behaviors. In 2010, he released his book, Whistling Vivaldi and Other Clues to How Stereotypes Affect Us, summarizing years of research on stereotype threat and the underperformance of minority students in higher education. In 2026, he released a second book, Churn: The Tension That Divides Us and How to Overcome It, which examines the anxiety people experience in diverse, high-stakes situations.
