I'm a science writer specializing in astronomy, geology, Earth and planetary science, climate science, ecology, and the environment. I enjoy sharing the wondrous and commonplace aspects of science; and strive to excite others into thinking, questioning, exploring, and seeing the world around them in a new light.

I've authored or co-authored four books and numerous news and feature articles for a wide variety of national and international publishers and organizations including: National Geographic, Scientific American, New Scientist, NASA, Space Telescope Science Institute, Capstone Press, and others. I'm a former associate editor of Astronomy magazine and was editor-in-chief of Astronomy.com.

I also develop multimedia educational tools and programs for museums, and am a consultant with the Space Telescope Science Institute developing ViewSpace programs that are seen in 300+ museums and science centers world wide.
