Dr. Elina Berglund Scherwitzl is the co-founder and co-CEO of Natural Cycles, the women's health company behind the world's first FDA-cleared birth control app. A particle physicist by training, Elina was part of the Nobel Prize–winning CERN team that discovered the Higgs boson. She then applied the same scientific rigor to a problem closer to home, developing the proprietary algorithm that powers NC° Birth Control, an FDA-cleared Class II medical device that uses biomarker data to determine daily fertility status with 6M+ registered users across the U.S., Europe, Canada, and beyond.
