I’m a Boston-based reporter and editor with many years of experience writing about energy and environment, technology, science, and business. I am currently Deputy Editor and Environment & Energy editor of The Conversation, a news analysis and commentary site written by academics and edited by journalists for a general audience. (Here is a Boston Globe profile and a report from the Nieman Lab on The Conversation.)

Before joining The Conversation, I was the national correspondent at Xconomy covering emerging technology and clean technology for entrepreneurs and investors. I also wrote regularly for MIT Technology Review, IEEE Spectrum, the Boston Globe, the Guardian Sustainable Business, Greentech Media, GreenBiz, and Scientific American. As an editor and a reporter, I’ve covered climate change and related issues in environment and energy from many different angles — science and technology, investment and business, as well as policy and politics.

Previously, I worked for 10 years at tech news site CNET, where I was the lead reporter and manager of the Green Tech blog. During the dotcom boom and bust, I was the executive editor of enterprise tech publication InfoWorld (bio).
