My working life has always centered around science and education, but writing fiction--mostly science fiction and fantasy--has been an accompaniment throughout; another mode of expressing thoughts and feelings about the world and universe. As a Peace Corps Volunteer I taught physics and math in Cameroon. I worked for ten years at research observatories, first NASA's Kuiper Airborne Observatory, and then at Lowell Observatory. Since 1999 I have been a staff astronomer and content researcher at Chabot Space & Science Center in Oakland, California.
