I work to create systems that can accurately detect pandemics early, determine their likely importance, and, with any luck, crush those that have the potential to devastate us.

We know there are certain types of viruses that are nasty - influenza, for instance, is an area that is not a blindside. But a lot of viruses have come out of nowhere, like H.I.V., or to a certain extent SARS. Because we know we have the potential to be blindsided, we really have to investigate the unknowns.

We may have charted all the continents on the planet, and we may have discovered all the mammals, but that doesn't mean that there's nothing left to explore on Earth.

Many people on our planet right now despair; they think we’ve reached a point where we’ve discovered most of the things. I’m going tell you right now: Please don’t despair.

If an alien visited Earth, they would take some note of humans, but probably spend most of their time trying to understand the dominant form of life on our planet - microorganisms like bacteria and viruses.

If you find diseases before they've really emerged, you can control them early on, before you get a major epidemic.

The world can now maintain an acute infection in a way that is unprecedented in the history of life on our planet.
