"I want to get young girls excited in science, tech, engineering mathematics, art, design - and how they come together. We've got this Choose Science campaign. Once women are there, though, we have to retain them. When I look at universities, it's not enough to have role models, we need to have champions. We need to have more women in senior leadership positions. There are issues about work-life balance. Women go to have children and then who keeps the lab running? There are many challenges."
