I'm the author of BRAZILLIONAIRES, which was a Financial Times best book of 2016 and a New York Times Book Review Editors’ Choice, and WHEN WE SOLD GOD'S EYE, a nonfiction finalist for the California Book Awards. A former Bloomberg reporter, I've also written for The New York Times Magazine, The New Yorker, Harper's, The Atlantic, and The Washington Post. My stories have been featured on Longform and in 2024's Best American Science and Nature Writing. I've received grants from the Pulitzer Center, the Fund for Investigative Journalism, and the Alicia Patterson Foundation.

Born in New York City, I grew up in Albuquerque, New Mexico, and studied creative writing and Latin American literature at Sarah Lawrence College. I started my journalism career as a freelancer in Bogotá in 2008 before moving to São Paulo to work for Bloomberg. There I was assigned to the billionaire beat — the basis for my first book. I lived in Brazil for six years and, for my second book, spent another six years visiting a tribe in the Amazon rainforest. I now live with my wife in San Francisco; outside work, I'm an avid rock climber.
