Colorado-based 11-year-old Gitanjali Rao was declared as the winner of the Top Young Scientist Challenge contest. She won $25,000 prize money. Rao is developing Tethys, a sensor-based device that can detect lead in water faster than other current techniques. She developed a mobile app that is cost-effective rather than using a costly equipment. Rao wants to be either a geneticist or epidemiologist in the future. She hopes to solve the water contamination crisis and reduce long-term health effects from the exposure of lead.
