Speaker bio: Dr. David A. Williams is a Research Professor in the School of Earth and Space Exploration at Arizona State University, Tempe, Arizona. Dr. Williams is the Director of the Ronald Greeley Center for Planetary Studies, a NASA-supported planetary data center at ASU. David is currently performing research in volcanology and planetary geology, with a focus on planetary mapping, geochemical, and remote sensing studies. His current research focuses on planetary geologic mapping of objects across the Solar System, and computer modeling of the physical and geochemical evolution of lava flows in a variety of planetary environments. He was involved with NASA’s Magellan Mission to Venus, Galileo Mission to Jupiter, Dawn Mission to asteroid Vesta and dwarf planet Ceres, and ESA’s Mars Express orbiter mission.  He is a member of the Italian JANUS camera team for the ESA Jupiter Icy Moons Explorer mission that launched in April 2023, and he is currently Deputy Imager Lead and a Co-Investigator on NASA’s Psyche Mission, which launched on October 13, 2023.  In 2014 David was elected a Fellow of the Geological Society of America, and the International Astronomical Union named asteroid 10,461Dawilliams in his honor.

Abstract: Jupiter’s moon Io is a bit larger than the Earth’s Moon but is by far the most geologically active place in the Solar System beyond Earth.  Dave Williams will review decades of remote sensing observations and monitoring of volcanic activity on this strange moon, including some of the most recent results from NASA’s Juno mission.  He will also look ahead to concepts for future Io missions.
