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 Science, Nature, the New York Times, Johns Hopkins Magazine, Inside Science, Science News, Wesleyan Magazine, Slate, Discover and Quanta.

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.
Writing – A nearly complete listing of my published work.
Editing – I have edited science stories, books, reports, blog posts and more.
Blog – Occasional essays and original reporting on a wide range of topics. Most touch on issues related to the environment and sustainability.
