Dianna Cowern is the creator of Physics Girl. Driving tractors on a farm in Hawaii where she grew up somehow led to science and engineering pursuits. Nicknamed “happy pants” in college, Dianna researched dark matter with Prof. Jocelyn Monroe as an undergraduate at MIT, and low-metallicity stars with Prof. Anna Frebel as a post-baccalaureate research fellow at the Harvard-Smithsonian Center for Astrophysics, before bringing her happy intern pants to GE where she worked as a software engineer designing mobile apps. Eventually, she started exercising the nerdy side of her brain on YouTube as Physics Girl before (and while) heading over to UCSD as a science outreach coordinator. She loves to surf, SCUBA dive and play the ukulele.
