Currently, I am a features editor for Nature magazine, working out of the Washington, DC, office. In my distant past-1975-I earned a Ph.D. in elementary particle physics at the University of Wisconsin, Madison. Two years later, in 1977, I earned a Master’s in journalism at Wisconsin. From 1977 to 1980 I was a writer and West Coast bureau chief for Chemical and Engineering News. From 1980 to 1991 I was a senior writer at Science magazine, where I covered physics, space, astronomy, computer science, artificial intelligence, molecular biology, psychology, and neuroscience. From 1991 to 2003 I was a freelance writer, and from 2003 to 2006 I worked in media affairs for the National Science Foundation. I am the author of Man-Made Minds (Walker, 1987), a book about artificial intelligence; Complexity (Simon & Schuster, 1992), a book about the Santa Fe Institute and the new sciences of complexity; and The Dream Machine (Viking, 2001), a book about the history of computing. In my spare time I am an avid cyclist. I live in Washington, D.C. with my wife, Amy E. Friedlander.
