"Nowadays, when you want to help the scientific development of your country, especially in Africa, you don’t necessarily have to return. The scientific production has several aspects: production, saving, transmission of knowledge. It is not enough to go and sit in a university in Africa, where we do not have the means to do so. By staying abroad, with collaborations, summer schools, long distance training, coaching… you can participate to the scientific development."
