Dianna Cowern is the creator of the award-winning YouTube channel Physics Girl, an educational series with PBS Digital Studios. She has reached over one million subscribers with 130+ videos on topics like, “How to create a vortex in your pool,” and “Why is the universe flat?” Through Physics Girl, public talks, and private workshops for teachers across the nation, Dianna explains exciting science topics, inspires kids—especially young girls—to pursue an interest in science, and rallies the general public to think critically through the wonder of science. Surprise cameos from Bill Nye, skateboard legend Rodney Mullen, and Anne Wojcicki (23andMe) have helped the channel receive over 78M views. Before starting Physics Girl, this Hawaii-raised MIT physics alumna completed a post-baccalaureate fellowship in astrophysics at Harvard, then worked as a software engineer at General Electric, and as UCSD’s physics outreach coordinator. Physics Girl has been featured on the Huffington Post, Slate Magazine, Scientific American blogs, and Popular Science.
