Gitanjali Rao Develops Lead Detection Device and Wins Stephen Hawking Medal
Gitanjali Rao began developing Tethys, a portable device to detect lead in drinking water, at age 10 after learning about the Flint water crisis. Her invention uses carbon nanotube sensors and Bluetooth to provide quick water quality results. At 11, she won the Discovery Education 3M Young Scientist Challenge, gaining national recognition. Rao later attended MIT and, at 19, became the first recipient of the Stephen Hawking Junior Medal for Science Communication, highlighting her ongoing commitment to science and social issues.
