I decided that it was worth my time to try to have some impact on that, and try to, first, help change the culture and make the culture realize that the girls are out there, that if we want scientists and engineers in the future, we should be cultivating the girls as much as the boys, and that we needed to be able to give girls in middle school, high school and college the same opportunities that we give to boys. So I have put in a lot of time creating programs for girls, particularly in middle school, to just keep them engaged and introduce them to role models, show them that whether they want to be a rocket scientist or a geochemist or a microbiologist, that there are women who are now actively involved in those careers and who love what they do. I think it’s slowly but surely having an impact.
