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

​

From April 2024 to April 2025, I am bicycling around the world. Read all about it on my blog, A Look Around.​

​

When I'm not in the saddle, I do research to enhance the well-being of diverse communities around the world. My employers have included Google, Meta, Stanford, and The World Bank. This New York Times article describes some of my work to fight bullying on Instagram.

​​

I also 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 on an adventure.
