I’m a Boston-based reporter and editor with many years of experience writing about energy and environment, technology, science, and business. In January, I began working at The Conversation, a news and analysis site written by academics for a general audience. I’m the Deputy Managing Editor and editor of the Energy & Environment desk.

Previously, I was the national correspondent at Xconomy covering emerging technology and energy 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. You can see stories by topic from the menu above.

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).
