Especially working in infectious disease, it's very interesting because these infectious diseases, these agents, they evolve over time.

The process of discovery in my field is very incremental. But there are moments when you realize you know something about the world nobody else knows. That's extraordinarily exhilarating.

You get these moments of thrill. There you are, at 3:00 in the morning, and you know something about how we evolved that nobody else in the world knows. It's a thrill of discovery.
