Welcome to my website. I’m a freelance journalist based in San Francisco, California. I write about materials science, nanotechnology, energy, computing, medicine, and physics. After over a decade as a science journalist, my favorite nanomaterial is carbon nanotubes and my favorite quasiparticle is the plasmon. If you don’t have favorites of your own yet, you should read some of my work. I’m a contributing editor at Technology Review, a contributor at Chemical and Engineering News, and I serve on the board of the Northern California chapter of the Society of Professional Journalists.

Local investigative gadflies at the San Francisco Public Press house freelancers including me in affordable office space–many thanks to them. Coworkers here include science writer Nathan Collins and radio wonder Lisa Morehouse.
