I write about science and the environment from Mount Rainier, Maryland, just outside the nation’s capital. I’ve written for science and general-interest publications including the New York Times, Science, Nature, Slate, Discover, Johns Hopkins Magazine, Wesleyan Magazine, Physics World, Inside Science, Science News and Nautilus.

Why tell stories about science? Science, like any other endeavor, has characters, plot, intrigue and heartbreak. But perhaps unique among human pursuits, it inevitably progresses: we always know more than we did before. I try to shed light on that process, showing what scientists know, what they hope to find out and why it matters.
Science – A nearly complete listing of my science stories. While I focus mainly on physical and environmental sciences, I have at one time or another written about almost every scientific field.
Blog – My blog features occasional essays and original reporting on a wide range of topics. Most touch on issues related to the environment and sustainability.
Education – From 2007 to 2011 I worked at the American Physical Society, where I wrote about physics and covered the education “beat.” I also wrote frequently about APS’s education and diversity programs, and continue to work on several projects as a consultant.
Radio – In 2012 I produced a series of pieces for the Perpetual Notion Machine, a science radio show in Madison, Wisconsin.
Multimedia – I have developed innovative posters, brochures, and videos on topics in physics and science education.
Music and Dance – I play traditional music and organize old-time music and dance events.
