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.

The features of globalization have huge consequences on pandemics. It just connects us so much more closely... And as a consequence, every one of these viruses that passes from animals to humans has the capacity to infect all of us.

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

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 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.

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

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.
