About the Author
Tracy K.P. Gregg is an Assistant Professor at the University at Buffalo in Buffalo, New York, USA. Her Lava Lab research group examines volcanic processes in extreme environments, ranging from mid-ocean ridges to Jupiter's Moon, Io. She has co-edited 3 books on Solar System volcanism, published more than 30 peer-reviewed papers and maps, and has supervised over 3 dozen graduate students since 1998. She has served as the Chair of the Planetary Geology Division of the Geological Society of America, and the Volcano-Ice Commission of the International Association of Volcanology and Chemistry of Earth's Interior. She was elected to be a Fellow of the Geological Society of America in 2012 and recently received the Distinguished Service Award from the Planetary Geology Division of the Geological Society of America. Rosaly Lopes is a Senior Research Scientist at the Jet Propulsion Laboratory, where she is also Manager of the Planetary Science Section. An expert on planetary volcanism, she worked on the Galileo mission to Jupiter and is currently on the science team of the Cassini mission to Saturn. Her research expertise is on volcanoes in the Solar System, particularly the active volcanoes of Jupiter's moon Io and the ice volcanoes of Saturn's icy moons. She is a Fellow of the American Association for the Advancement of Science and the Geological Society of America, and the winner of the American Astronomical Society's 2005 Carl Sagan Medal. She has published seven books and over one hundred and twenty peer-reviewed publications Sarah Fagents is a Researcher in the Hawaii Institute of Geophysics and Planetology at the University of Hawaii at Manoa. She investigates volcanic features and eruption processes on the Earth and other planets, and is a member of the science team of the upcoming Mars 2020 rover mission. Her publications cover a wide range of volcanic subject matter, including magma-water interactions, explosive volcanism on Mars and Venus, lava flow dynamics and heat transfer, and cryovolcanism on Jupiter's moon Europa. She shares her enthusiasm for planetary volcanism with the public whenever possible.
