Prof. SMITH?: It was actually a class project. I was teaching a course in disease modeling. And I said to the students, you can do anything you like as long as it's disease. And one group came up and said, well, we have an idea, but it's a little bit out of the box. And I said, sure. You know, what have you got? And they said, zombies. And I think they thought I'd shoot it down, but actually I said, go for it. That sounds really great.
And it was just a fun way of really illustrating some of the process that you might have in modeling and infectious disease.
