I'm a geologist who specializes in the geochemistry of weird elements, weird bacteria, and weird planets. I'm a skeptic, a blogger, a cat herder, and quite the slacker. I fight the forces of ignorance and superstition through my heroic blog, which features news and commentary from sundry fields of scientific endeavor. Also I rant.
