Dianna is the always enthusiastic, ever curious, creator and host of the highly successful YouTube channel Physics Girl. She’s especially passionate about science, education and sparking a lifelong curiosity in science for girls and minorities.


Hawaii born and raised, Dianna was inspired by physics as a girl. Thanks to encouragement by her teachers and family, she pursued a physics degree at MIT. She subsequently explored careers in scientific research (at the Harvard-Smithsonian Center for Astrophysics), software engineering (at General Electric) and science outreach (at the Reuben H Fleet Science Center and the University of California San Diego) before committing to the Physics Girl YouTube channel full-time.

Dianna loves sharing her curiosity with her 1.3 million subscribers and beyond, and she was recently named as one of Forbes 30 under 30. Her time is split between writing, filming and producing content for her YouTube channel; and public speaking engagements at conferences, universities, classrooms, and further afield. She lives in San Diego and loves to get out on the water surfing.
