Infectious disease exists at this intersection between real science, medicine, public health, social policy, and human conflict. There's a tendency of people to try and make a group out of those who have the disease. It makes people who don't have the disease feel safer.

Margot Livesey, my dear friend, reads all the drafts of what I write, and I read hers. We have an intense working relationship. I've been really lucky to know her. She's a great reader and teacher as well as an astonishingly good writer.

I wanted to be a scientist. My undergraduate degree is in biology, and I really did think I might go off and be some kind of a lady Darwin someplace.
