The biggest killers of children around the world are two things: diarrhea and pneumonia. When you think about it, in the United States, kids don't die of diarrhea anymore, but it's a huge problem in the developing world.

We start with an economic approach. We look at what are the greatest causes of death in the developing world, and what causes the largest amount of disability, which would prevent you from getting a job. A lot of those deaths start with diseases, diseases we don't get in such a great number in the United States.

We also ought to recognize that unpaid labor falls predominantly to women. The other thing I would do in countries like the U.S. is to show more men, even in TV ads, doing household work. Only two percent of ads show men doing chores, and yet we know they actually do several hours of it in real life. Those images affect young boys and girls.

Women around the world should have a tool that helps them plan their pregnancies.

Human-centered design. Meeting people where they are and really taking their needs and feedback into account. When you let people participate in the design process, you find that they often have ingenious ideas about what would really help them. And it’s not a onetime thing; it’s an iterative process.

Women are the centre of the family. It's the woman who decides what's eaten in the house, when to have the kids vaccinated; everything that has to do with the children's health revolves around her.

We also look at farming. Are we making sure that we're getting the latest seeds out to women so they can get a bigger yield off of their farms? A new type of seed that gets out to a man, let's say, that's drought resistant - because, of course, the rains are changing in Africa with climate change - if you don't put it in the hands of a woman, she won't necessarily get it. We look at breaking down all those barriers.
