As an audience cheers, three teenage girls cross the stage in a line, to the high-energy beat of The Chainsmokers' "Don't Let Me Down." They're dressed in head-to-toe black, but each of their shirts is decorated with bright bulbs, flashing and blinking in various colors as they move.

The performance is a product of STEM From Dance, a New York City-based nonprofit founded by Yamilee Toussaint—an MIT grad who's been dancing since age 5. The program targets middle and high school girls of color, who are vastly underrepresented in STEM (science, technology, engineering and math) fields, and might not otherwise see STEM as an option or be encouraged to try it.
