Lopes is a Senior Research Scientist at NASA's Jet Propulsion Laboratory, where she is also Manager for Planetary Science. She has a B.Sc. in Astronomy and a Ph.D. in planetary geology from University College London (University of London, UK). She has spent most of her career at NASA’s Jet Propulsion Laboratory working on the science teams for the Galileo and Cassini missions and pursuing research on planetary and terrestrial geology, particularly volcanology. She has visited active volcanoes in all continents and discovered 71 active volcanoes on Jupiter’s moon Io. In 2006, she was elected Fellow of the American Association for the Advancement of Science and, in 2015, Fellow of the Geological Society of America for her contributions to the studies of volcanism on Earth and the planets. Dr. Lopes has written more than 120 peer-reviewed scientific publications and seven books. In addition to her science work, she is a strong supporter of education and outreach, nationally and internationally. She has received numerous awards, including the Carl Sagan medal from the American Astronomical Society.
