David Epstein

David Epstein is an American journalist, author, and podcaster specializing in science, sports science , and investigative reporting. He holds master's degrees in environmental science and journalism from Columbia University , and has unique field experience including living on a ship in the Pacific Ocean and in a tent in the Arctic during his studies.

Epstein's career began as the first reporter for Inside Higher Ed and a crime reporter for the New York Daily News , before advancing to senior writer at Sports Illustrated , where he co-authored a prominent 2009 investigative report exposing Alex Rodriguez's use of steroids. He later joined ProPublica as a science and investigative reporter, covering topics such as flawed medical practices, muscular dystrophy genetics, and the DEA's operations against drug cartels, including the pursuit of rivals to Joaquín "Chapo" Guzmán. His work at ProPublica earned him awards from organizations including the National Academies of Sciences, Engineering, and Medicine and the Society of Professional Journalists .

As an author , Epstein has written two New York Times bestsellers: The Sports Gene: Inside the Science of Extraordinary Athletic Performance (2013), which explores the interplay of genetics and training in athletics and was purchased by figures like Barack Obama and Condoleezza Rice , and Range: Why Generalists Triumph in a Specialized World (2019), a #1 bestseller translated into over 30 languages that argues for the advantages of broad experience over early specialization. He is also the author of the forthcoming book Inside the Box: How Constraints Make Us Better (2026). He also hosted Slate's popular How To! podcast and writes the Range Widely newsletter on human performance science . His TED Talks, viewed over 12 million times, further popularized his ideas on specialization and athletic performance. Three of his stories have been optioned for film adaptations, and he received an honorary doctorate from Drew University in 2025.

David Epstein was born in 1980 in Chicago and grew up in a suburb outside Chicago . His hometown featured a notable mini-Jamaican diaspora , which created a vibrant multicultural environment that profoundly shaped his early worldview and interests. This community included many Jamaican immigrants and first-generation Americans , exposing Epstein to diverse cultural influences and sparking his fascination with human performance and variation from a young age.

Epstein's early athletic involvement centered on track and field , where he competed as a distance runner during high school. His team enjoyed extraordinary success, securing 24 consecutive conference championships, primarily driven by the exceptional talents of Jamaican sprinters on the roster. Observing these athletes' dominance despite shared training routines ignited Epstein's curiosity about the interplay between genetics , environment, and athletic ability, laying the groundwork for his later explorations in sports science . He trained alongside Jamaican runners in high school, which highlighted disparities in speed; he later trained with Kenyan runners in college, further emphasizing differences in endurance .

Details about Epstein's family background remain limited in public records, with little documentation of specific parental professions or direct influences on his development. Nonetheless, the diverse early environment of his Chicago suburb appears to have been a key formative factor, nurturing his budding interests in science and athletics without reliance on familial anecdotes. These experiences in youth athletics not only honed his physical skills but also directed him toward questioning the biological underpinnings of talent, influencing his path before entering higher education.

David Epstein earned a bachelor's degree in environmental science and astronomy from Columbia University in 2002.
