I am a free-lance writer of non-fiction and fiction. I studied at Oxford (DPhil, Rhodes Scholar), Harvard (BA, summa cum laude), and Alief Hastings High School in rural east Texas, home of the Fighting Bears. After that, I worked as an associate in M&A at Goldman Sachs in their London and Frankfurt offices, and I studied classical guitar in Seville, Spain with América Martínez, a disciple of Andrés Segovia. I've lived or worked in 48 countries.

My most recent book, How to Make a Killing, is a look at the shocking world of the US healthcare through the lens of the dialysis industry, where a miracle cure has become a nightmare for many patients. My previous books are: Crisis of Conscience, is a cultural history of whistleblowing and fraud, published in October, 2019 by Penguin Random House (in their Riverhead imprint) in the US, and by Atlantic Books in the UK and Commonwealth countries; and Extra Virginity, a New York Times best-selling account of olive oil culture, history, and crime, published by W W Norton. My articles have appeared in the New Yorker, National Geographic Magazine, New York Times Magazine, Atlantic Monthly, and elsewhere, and have been included in anthologies like Best American Science Writing and Best American Travel Writing.
