Thrive Global and The Quaker Oats Company present The Fuel List—20 people changing the way we fuel our minds and bodies every day. These are the leaders making an impact in the worlds of sleep, nutrition, movement and mindfulness right now.

Dr. Wendy Troxel is putting hard numbers behind the impact sleep loss has on us on a professional level. As a senior behavioral and social scientist at the RAND Corporation and an adjunct professor of both psychiatry and psychology at the University of Pittsburgh, Troxel researches the economic toll of sleep deprivation, and she’s become a go-to expert on how being deprived affects our job performance. She’s also one of the scientists leading the charge for later school start times—her 2016 TEDx talk, Why School Should Start Later for Teens, has been viewed more than 1 million times. Troxel has a knack for taking complicated scientific issues and presenting them in a way that makes people stop and pay attention—an invaluable skill when we’re talking about something as important as sleep.

“Wendy Troxel is on the front lines of the sleep revolution. Again and again, her research shows just how fundamentally sleep affects every aspect of our lives, from our job performance to the health of our economy. And I hope her work on delaying school start times will spur widespread reform so that children and adolescents can get the sleep they need.” — Arianna Huffington, Thrive Global Founder and CEO
