I’m a writer based in Seattle who has had the good fortune to write about some of the most interesting and important topics of our time, including genetics, race, human origins, evolution, climate change, education, talent, competition, and punk rock music. Here’s a short bio. For a longer summary of my 30-year career as a freelance writer, here’s a resume.

I haven’t done much magazine work since moving to Seattle a year or so ago, but recently the Princeton Alumni Weekly published an article of mine on the geometric structure of musical chords.  It turns out that any piece of music can be represented as a sequence of movements within a non-Euclidian multidimensional space called an orbifold.  This is an idea that probably appeals mostly to musically inclined mathematicians or mathematically inclined musicians, but as someone who has written books about both math and music, it appealed to me.
