The tool that's most associated with the recent progress against malaria is the long-lasting bed net. Bed nets are a fantastic innovation. But we can do even better. We can invent new ways to control the mosquitoes that carry the malaria parasite.

We're still missing about a dozen vaccines that will make a huge difference. For adults, we've got HIV and TB are still huge; for kids malaria is still killing a half million kids a year out of that 6 million. We probably need some vaccines, but we need a little more data to make sure we're getting the vaccines that will save the most lives.

In energy, you have to plan and do research way in advance, sometimes decades in advance to get a new system that's safer, doesn't require us to go around the world to get all our oil.

I can understand wanting to have millions of dollars; there's a certain freedom, meaningful freedom, that comes with that.

I would counsel people to go to college, because it's one of the best times in your life in terms of who you meet and develop a broad set of intellectual skills.

In almost every area of human endeavor, the practice improves over time. That hasn't been the case for teaching.

My fascination is broadly with biology and the fact that our increased understanding of biology allows for breakthroughs in a broad set of diseases.
