Brianna Rapini, also known as Pinky on the Amoeba Sisters YouTube Channel, dreamed of becoming a biology teacher since she was a little kid. Over the course of twelve years in public education, Brianna wore many hats, including classroom biology teacher, instructional technology specialist, campus science specialist, and district science coordinator. In a plot twist, Brianna and her sister, Sarina Peterson, stumbled into YouTube fame with the birth of their channel, the Amoeba Sisters, which has become a staple for biology students and teachers alike. After Brianna went on to get her master’s in biological sciences, she realized Amoeba Sisters will never run out of introductory biology content to cover. There’s still so much biology to learn, and she loves to emphasize to viewers that she continues to learn new things.
