In her 1925 PhD thesis, she proposed an explanation for the composition of stars in terms of the relative abundances of hydrogen and helium. In 1931, she became an American citizen. On a tour through Europe she met Russian-born astrophysicist Sergei I. Gaposchkin. She helped him get a visa to the US and they married in 1934.
