I spoke to Koch a few months back when I was writing about consciousness for the New York Times. Afterwards, he sent me an email.

I do have plenty of engineering tattoos in the Science Tattoo Emporium, but I paused at Koch’s. Tools, yes. Brands?

So I asked Koch what this tattoo meant to him.

Koch’s new job seems like the perfect opportunity to post his picture. Who knows how many other tattooed scientists are taking over the reins of power?
