I'm an author and journalist. I write mostly about health, technology, and society. I'm a longtime contributor at Time magazine, and my work has also appeared in The New York Times, The Washington Post, The Financial Times, Vox, and elsewhere. I'm originally from Michigan, but these days I live with my wife and kids in the Black Forest region of Germany.

My book The Habit Trap: How Our Routines Hold Us Back will be published early in 2027 by the Harper imprint of HarperCollins. You can learn more about me and my work at markhamheid.com.
