Black scientists have been historically underrepresented in academia and science. A 2018 study of the National Center for Education Statistics found that only 6% of faculty in the USA were Black. Systemic racism and other issues that translate into a lack of diversity in research often cause unwelcoming environments for Black scientists. Last fall, sparked by the Black Lives Matter movement and triggered by the #BlackBirdersWeek virtual event, several scientific communities took to social media to create ‘#BlackIn...’ movements. Over the course of a week, organizers offered virtual talks, workshops and social events highlighting Black scientists in their fields. We spoke with the founders of four of these ‘#BlackIn...’ movements to learn how they are empowering the Black scientific community to start conversations about being Black in science, and to discuss strategies for continuing to diversify scientific research.
