In 1942 she left Memorial Hospital and joined the Center for Radiological Research, led by Failla, at Columbia's medical school, where she worked until 1978. Her research at Memorial Hospital delved into safe doses of medicinal radiation, observing the energy emitted by potential materials for nuclear medicine as well as the amount of radiation absorbed by the body from different sources. She also studied the potential of synthesised radioactive materials for treating cancer and in other medical research applications.
