Frances Kraus is a physicist specializing in x-ray spectroscopy of hot plasmas. She completed undergraduate studies at the University of Alabama before obtaining a PhD in Princeton University's Program in Plasma Physics in 2021. Frances maintains a skepticism of the unobservable and thus focuses her research on measuring things, checking assumptions and analyzing data without prejudice. Pursuit of these goals has led to investigations of plasma sheath structure and laser interactions with solids, the latter under the auspices of the LaserNetUS consortium. In addition to research, Frances enjoys engaging anyone and everyone about science, in part via the Princeton FM radio station WPRB and as the elected Vice Chair of the American Physical Society's Forum on Outreach and Engagement of the Public.
