Anne H. Peslier

About the Author

Anne H. Peslier is a distinguished geochemist and research scientist at NASA's Johnson Space Center, where she applies her expertise in mantle petrology and volatile geochemistry to unravel the mysteries of Earth's deep interior and planetary formation. With a Ph.D. from the University of Paris and extensive fieldwork in volcanic regions worldwide, Peslier has pioneered analytical techniques using Fourier Transform Infrared (FTIR) spectroscopy to quantify water and other volatiles in mantle minerals. Her groundbreaking research on the Slave Craton in Canada has provided critical insights into the hydration state of the cratonic mantle, influencing models of tectonic stability and diamond formation. Beyond academia, she contributes to space exploration by studying lunar and Martian samples, bridging terrestrial geology with extraterrestrial science. Peslier's work, published in leading journals, continues to shape our understanding of planetary evolution.
