Hello! A Wyoming child, I love words and the natural world. In mid career as an astrophysicist, I study galaxy evolution and I know a fair bit about spectroscopy. This blog is an outlet for me to explore a broader range of topics than the merely technical. I discuss science, writing, music, critical thinking, and I slip in updates on Ace Carroway, adventurer extraordinaire.


There are book-related sites at which you can “follow” me, if you’d like.

Occasional “sales” and “deals” might pop up now and then at these places.

You can contact me with the following form. It just sends me an email. Don’t be shy. I like to chat (with entities that are not robots, that is). I have a newsletter, emailed only at new release time. Use this form if you’d like to be on the email list. (Secret: I give away books to people on that list.)
