From 1944 to 1945 she was employed as a physicist at the Naval Ordnance Laboratory. Then for the next twenty years, from 1950 to 1970, she was a Research Associate, at the University of Minnesota, Minneapolis. She stayed at that university and from 1970 to 1975 she was an Associate Professor, and from 1975-1992 she was a Professor of Physics.
In addition to her contribution as graduate student, mentioned above, she also published other significant contributions in the fields of particle physics, geophysics, and astrophysics that covered nuclear emission spectra, cosmic rays, and applying nuclear emulsions.
