I am a cultural scientist who studies how cultures shape people's thoughts, feelings, and actions.

By day, I do research to enhance the well-being of diverse communities around the world. My employers have included Google, the Stanford School of Medicine, and The World Bank. This New York Times article describes some of my work to fight bullying on Instagram.

By night, I write books like Clash! How to Thrive in a Multicultural World (with cultural psychology pioneer Hazel Rose Markus) and sundry articles.

Previously, I served as founding executive director of Stanford SPARQ, vice president of content at The Tech Museum, and senior editor of the Stanford Social Innovation Review.


A native of Memphis, I am now based in San Francisco when I am not out bike touring or mountain climbing.
