Dr. Rosaly M. C. Lopes is a Senior Research Scientist at NASA's Jet Propulsion Laboratory, where she is also Lead Scientist for Geophysics and Planetary Geosciences. Dr. Lopes was born and raised in Rio de Janeiro, Brazil, where she grew up by the famous Ipanema Beach. She moved to London, England, to study astronomy at the University of London, from where she graduated in 1978. For her doctoral studies, she specialized in planetary geology and volcanology and completed her Ph. D. in Planetary Science in 1986. Her major research interests are in planetary and terrestrial geology and volcanology. During her Ph.D. she traveled extensively to active volcanoes, particularly Mount Etna in Sicily, and became a member of the U.K.’s Volcanic Eruption Surveillance Team. Dr. Lopes joined JPL as National Research Council Fellow in 1989 and, in 1991, became a member of the Galileo Flight Project, a mission to Jupiter. She was responsible for observations of Jupiter’s volcanic moon Io from 1996 to 2001, using Galileo’s Near-infrared mapping spectrometer. During this exciting period of her career, she discovered 71 active volcanoes on Io, for which she was honored in the 2006 edition of the Guinness Book of World Records as the discoverer of the most active volcanoes anywhere.
