The Christa McAuliffe Center at Framingham State University will present a hybrid event on November 9, 4:30PM-6PM:  A panel discussion with the producers and cast members of Central Square Theater’s Young Nerds of Color. The play weaves together interviews with scientists from underrepresented backgrounds to explore implicit and systemic bias that young people of color face when trying to enter STEM fields — and the resulting loss incurred as a result. You do not need to see the play to enjoy the discussion, but all are encouraged to see the play. Register for the Zoom session or walk-in for the in-person event.
