As head of the AAVSO for over 30 years, she collected observations of variable stars by amateur astronomers from around the world. She coordinated many important observing programs between amateur observers and professional astronomers. She was also keenly interested in education and student science projects. Under her direction, the database of the association was made available to educators and also assisted non-professional astronomers access the Hubble Space Telescope.
