All 35 of these people are doing exciting work that could shape their fields for decades. But they’re solving problems in remarkably different ways. We consider some of them to be primarily Inventors; they’re immersed in building new technologies. Others we call Visionaries, because they’re showing how technologies could be put to new or better uses. Humanitarians are using technology to expand opportunities or inform public policy. Pioneers are doing fundamental work that will spawn future innovations; such ­breakthroughs will be taken up by tomorrow’s Entrepreneurs, ­people who are building new tech businesses.

Everyone on the list was nominated either by the public or by MIT Technology Review’s editors. Some got our attention when they were picked by our international publishing partners as Innovators Under 35 for their regions. After our editors pared the roughly 500 nominees to 80 finalists, outside judges rated the originality and impact, or potential impact, of their work; those scores guided the editors as they crafted the list.
