Jack Andraka’s STEM inventions are helping detect cancer, fight water pollution, identify neglected tropical diseases and redefine global health approaches. It may come as a surprise to learn that this National Geographic Emerging Explorer is only a junior at Stanford University.

“The most rewarding part about inventing to me is when my invention is used by the communities and individuals I set out to help,” Andraka said. “The feeling you get from the knowledge that something you created is helping improve the lives of people is this amazing combination of joy, pride, empathy and humility from recognizing that you could make a positive change in collaboration with your communities.”
