Pierre and Marie Curie were similar to modern day theoretical physicist Michio Kaku. Similar to the Curies, Kaku frequently publishes scientific papers to keep information on various observations in the scientific community. Also, Kaku often goes into risky parts of science were there is still very debatable data such as information about string theory. The Curies would most likely be in the field of cancer research or radiation treatment because, although it has changed plenty within over a hundred years, it still has the same foundation of research and better safety standards.
