Women make up less than a quarter of STEM professionals in the U.S., and numbers are even lower for women of color. But a growing group of researchers is exposing longstanding discrimination and making science more inclusive. An official selection of the Tribeca Film Festival, Picture a Scientist follows three women—two of whom are affiliated with universities in Boston—who lead viewers on a journey into their difficult workplace experiences.

Watch Picture a Scientist on NOVA, tonight at 9pm on GBH 2
