A low-power, multiroom sensor network watches for drips and runs on a coin-cell battery.
I’m a freelance science and technology journalist based in San Francisco. I was the information technology editor at MIT’s Technology Review from 2005 to 2009, where I wrote more than 350 stories about emerging technologies in areas that include computers, mobile devices, displays, communication networks, Internet startups, and more.
I was an integral part of a technology trend-spotting team, highlighting early work in reality mining, plasmonics, adaptable networks, and racetrack memory. I’ve contributed to The Economist, U.S News & World Report, Gizmodo, New Scientist, Science News, and SELF, among other publications. And I’m currently working on a book with Nathan Eagle called Reality Mining: Using Big Data to Engineer a Better World (MIT Press).
