After a decade in research astronomy and a decade in journalism, I became a K-12 teacher, textbook contributor, and adjunct professor in physics, astronomy, and related sciences. I'm especially interested in hands-on, inquiry-based activities using everyday materials, and in the growing universe of open-source textbooks, software, and courses.
